First, I need to start this review by saying that when it comes to cordless phones, nobody beats Panasonic. I don't work nor am I affiliated with Panasonic. This comes from someone that has been using a multitude of different cordless phones over the past few decades.For the past two years I have owned Panasonic's TG-5566 5.8 Dect phone with multiple handsets. This was a powerhouse of a cordless phone system complete with a nice color screen and flashing antenna when calls and voicemail arrived.I wanted to upgrade because the 5.8 phone just wouldn't cover my large property. If I wanted to walk the dog and talk outside, I couldn't because of the lack of range. I couldn't even talk on my deck, located on the opposite end of the house from the base unit.I was eyeing the TG7875S for a long time, but hesitated to upgrade. First, it had no color screen that I could upload a picture to (my old phone was able to accomplish that). Next, it had no flashing light antenna to indicate new voice messages. Thirdly, reading the Amazon reviews from actual owners, I got the idea that this would be sort of a downgrade to all the "bells and whistles" that Panasonic had put into their older phones.I am so happy that I took a leap of faith and ordered the KX-TG7875SBeen using it for a week now, and I must say, I love it more than my previous phone system.First of all, before you even buy the phone it's a good idea to do a Google search for the manual to get an idea of all the things you can do with this phone. That being said, I was a bit fearful of all the menu codes mentioned in the manual that gave a person quick access to primary functions. How in the hell would I remember all these codes? Well, rest assured, everything is easily accessible through the phone's handset navigation screen. Play around with it a little, and you'll find that you can easily access any function of the phone within seconds from the navigation screen.The best thing about the Dect 6.0 is its range. I get far more range across my property with this phone than I did with the older. However, I still can't get a signal to the far end of the property. That problem was remedied when I purchased the TGA405B range extender. What a remarkable little unit that thing is. It almost doubled the signal and allows me to walk to the edges of my property without any signal loss. I'll talk more about this device again in a moment.I read complaints about Speakerphone and handset volume. I had none of these issues. Both work well, and there are controls to raise the volume on both. The base unit has a built-in answering machine, but I turned it off since I subscribe to voice mail service. For those subscribers like myself, you will obviously by dismayed by the fact there are no flashing lights to indicate a new voice message is awaiting you, however, a message is clearly displayed across the base and handset that a new voice mail message is waiting.Link2Cell works wonderfully -- much better than what I was using previously. When I had the older Panasonic phone I bought a xLINK device that would plug into the phone line and pair a cell phone. It was bluetooth based, like the new Link2Cell, but it had very limited range. I was amazed at how much better range the bluetooth coverage is on this phone. It easily linked with my iPhone 6 Plus. The base station is located on a top floor, at the opposite end of a large home. However, upon entering the front door, my iPhone automatically links with the base station. It's incredible, because with the previous device I was using, it would only link up if I was in the adjoining room. So bravo to this unit for its bluetooth range.So, yes, once you have your cell phone linked up, when that phone rings, so does your Panasonic phone system. Even caller ID from the cell phone is forwarded to the Panasonic display screen. Call quality is very good, but of course, dependent upon how strong your cell phone signal is. I have dead spots in my home so the quality of the calls from my cell phone vary.What I really love is when someone sends a text message to my iPhone and I get a notification on my Panasonic phone. It's really cool to hear the Panasonic phone ring and a voice say "Text Message."So, essentially, the Panasonic TG7875S allows you leave your cell phone in its charger and completely forget about it when you are home. Your cell phone calls will be forwarded to the base and handsets. If you get a text message, you will be notified of it.I knew I didn't need 5 handsets (I actually needed only 4), but I put a spare away just in case one ever fails. The handsets can be customized with individual names such as "Ron Office" or "Living Room." Intercom functionality allows you to call from one handset at one end of the house to another. I also believe (though I have not tested this) that someone can pick up a handset and join someone on another handset in a single call.Panasonic has introduced two great add-ons to this phone that I think is well worth considering. The first is something I previously mentioned in this review: the TGA405B range extender. It will literally almost double the signal strength of your cordless phone system. So, if you have a large yard and wish to have the ability to walk it and talk it, then this is a must purchase accessory. It costs just under $30. Next, is the TGA20B Key Detector. Clip it on your keychain and use your Panasonic handset to locate your keys if you have misplaced them. The device is nice and small, but my only complaint is that the "chirp" from it could be louder. Thankfully, the Panasonic handset gives you increased/decreased signal strength as you approach (or walk away from) the keys. So even if you can't initially hear the "chirp" of the device the Panasonic phone should be able to guide you there.I think I have covered everything. Just want to again say that this is a remarkable phone system. With the addition of the range extender and the keychain finder, it becomes an INCREDIBLE phone system. So happy I didn't take the less than stellar reviews to heart and bought this phone system.Previous, we’ve owned two sets of wireless Panasonic home phones. The most recent was a forerunner version of the Panasonic Link2Cell Bluetooth phones. Base upon our experience one can expect these phones to last approximately five (2009 to 2015) to eight (2000 to 2008) years. This life expectancy is typically longer than most people keep their cell phone, so when you project the cost out over the years it seems pretty reasonable.Some issues with the old phone system were: push buttons stopped working, ringers on some of the phones stopped working and the speaker phone on one of the phones stopped working. The old system didn't allow for adding an additional phone, but this system allows for adding an additional telephone. Further, the old phones were quite limited with the number of names and phone numbers that could be stored in them. Though we've only had the new phones for a couple of month, the new system seems to be satisfactory. There are many more features with these phones.The set up for “programming” or setting up the various features could initially be intimidating but it is really not that difficult. It is based upon entering #, followed by the appropriate code number. All the codes are included in the Operating Instructions. It maybe a little confusing if you've never used such a system, but it is relatively straightforward after going through a couple of entries. Just make sure you hang onto your Operating Instructions.We have not and do not intend to link this system to our cell phones through a Bluetooth connection. Voice mail is a component of this phone system as well as our cell phones. Missing a call on occasion isn’t a crisis - in fact, sometimes we don’t want to answer either.ProsYou may use the prerecorded greeting for voice messages or you can make your own.I like the voice caller ID, though it does come up with some rather amusing pronunciations.As with our previous Panasonic systems, the names and phone numbers need only be entered into one handset. Once entered, they will appear in all the handsets.We like the call “block feature” - it allows you to apply the call block to those repeat offenders you don’t want to hear from. The “missed call” feature captures the phone numbers of all incoming calls. This allows you to pick those numbers you wish to add to the call block. It also allows you to call back those numbers you wish.A flashing light on the base set provides notification of new messages. I understand that you can have the phone provide beep alerting you for as well. These features can be turned on or off by changing codes. You have the ability to “name” each handset, i.e., study, bdroom, shop, kitchen, etc. and each handset is numbered.The intercom feature allows you to speak from one handset to another, i.e., from the kitchen to the shop. However, I think the most important function of the intercom is as an aid to find misplaced handsets by calling the missing handset. When the livingroom handset disappears, it’s easier to find it underneath the cushion on the couch using the intercom.The reception of the wireless units is satisfactory for our purposes. I have one handset in my shop, a metal structure, approximately 103 feet away from the kitchen base unit (yes, maybe a bit anal retentive, but I measured it). I have read reviews to the contrary - all I can say is: mine works fine at that range.The Panasonic Link2Cell Bluetooth phones can store up to 3,000 names and telephone numbers, which is far more than any of the previous Panasonic phones we’ve owned.We like the speaker phone feature of these phones.These phones are also equipped with a noise reduction button on the handset to reduce background noise coming from the other party’s telephone. The handset also has a “handset equalizer” that supposed to help make it easier to understand the person you’re speaking with. I’ve used the noise reduction feature but not the handset equalizer. Does the noise reduction feature work? Probably/maybe. When I used the noise reduction feature, I could hear the person to whom I was speaking - I cannot actually say it made it easier for me to hear them . . . but I could hear them.This phone system has many features - many more than I’ll ever use . . . but you can if you wish.ConsThere are three options to store numbers in the Phonebook: Home, Cell1 and Cell2. This feature is fine for those who wish to pair their cell phones with this system, but we don’t. To expedite finding numbers, we store family members as “Home,” friends and other frequently called numbers are stored in “Cell1,” and businesses are stored in “Cell2. ” I’d prefer to be able to name the categories, but that’s a minor issue.While there is a flashing light on the base unit to provide notification of new voice messages, the only notification on the handsets is a message that appears on the screen, “New Message Press PLAY.” While this is better than nothing, it could be easily over looked. Previous systems had a flashing light on the handsets as well as the base unit.The back lighting of the keys could be improved, as they are difficult to see, particularly if you answer a call at night in the dark. One has to rely more on familiarity with the phone than actually being able to see the buttons.SummaryThis phone system has been better than I expected, so far. We’ve had no issues with it, but it is still relatively brand new. As the owner of two earlier wireless Panasonic phone systems, I had an idea of what I was getting and what I expected. To date, this system has been superior to our previous Panasonic systems and it has more PROS than CONS.I've had other Panasonic hands sets over the years, including my previous set. This model was HIGHLY rated but the sound quality is actually POORER than the previous Panasonic Handset I had. This model looks great, the keys are nice and big and LIGHT UP. The base station is very nicely laid out and I REALLY wanted the phonebook that is centralized (meaning that you can save a new phone number to any one of the hand sets and it will show up on all the hand sets). In some older and current models, you have to add phone numbers to each and every hand set individually which is seriously a pain in the butt and not user friendly. This model HAS the centralized phonebook feature. BUT the most important feature of a phone is the SOUND QUALITY and this is surprizingly mediocre on this model, especially when placed on speaker mode. In speaker mode you hear alot of extraneous background noise and the maximum volume setting isn't really loud enough. Quite Disappointing especially given the price of this model. It should have top-notch and its merely average.I have had these phones for just over 2 months and the sound quality, range, feel is great. My only gripe is the labels describing the actions for the thumbpad are already starting to fade, I can barely make out the 'redial' label as it has almost entirely smudged off. Same for the address book icon and CID is starting to fade too. 3 stars because of how ugly it is starting to get after 2 months of casual use (I use my cell phone way more than the land line which is mostly used for socializing with the local window installers) and because the phone wasn't exactly cheap!Este kit de Panasonic es genial. Llene la casa de teléfonos y ahora puedo hablar de donde sea. La contestadora automática con que cuanta la base es muy fácil de usar. Puedes hacer llamadas locales en tu casa llamando a cada uno de los handset's así mismo puedes configurar dos equipos celulares vía Bluetooth para recibir las llamadas de estos en cualquiera de los 5 handset's. Un excelente kit telefonicoI have only had the phones for less than 1 year and the display screens already don't work, the clips broke off so easily and 2 of the batteries don't last longer than 3/4 hours off the base ... Won't buy them again. Very disappointed with these phones. Will be looking into the warranty on them. I just want to point out too that we are a Panasonic family so this experience was shocking!Works well. Like using standard rechargeable batteries so more affordable when need to replace them.Was easy to connect to my cell.Wish I could turn off the text announcements as the phone rings every time a new text message come in when my cell is paired to it. Annoying. If it would beep or some less intrusive tone for announcing new text messages it would be much better.
