I have owned Panasonic cordless phones for decades. They are always my first brand of choice when upgrading my phone system.Recently, I got rid of my landline phones. It would be much cheaper to rely on my cellphone. However, I also wanted the convenience of talking on a handset.The great thing about this cordless phone system is its ability to connect to up to 2 cell phones. Once connected, it works rather well, though there are minor downsides.First, you need to place the Panasonic base unit next to where you will keep your cell phone. Since the connection is Bluetooth, there isn't much distance to play with and both units will need to be close to communicate with each other. You can certainly take your cell phone with you when traveling outside of your home, but once you return, you will need to place it near the Panasonic base unit again where the Bluetooth connection will re-establish itself automatically.There is a setting on the Panasonic phone that puts it in "cellphone only" mode. This gets rid of the constant message that appears on the screen that indicates you are not connected to a landline.Making calls on the handset while connected to your cellphone isn't quite as fluid as I had hoped, but it works well. You need to dial the number you want, press the CELL button beneath the screen, and then there is a brief pause and a few beeps until the phone connects.Cell phone quality is excellent. There is no breakup, no crackling. The only issue I found is that the overall volume level could be a bit better. I had the volume turned all the way up on the handset and thought that it still could have been louder. Then again, I am over 60 years old and my hearing isn't as good as it used to be.Caller ID information is transferred from your cell phone to the Panasonic handset, and a voice will not only announce the caller but also inform you when a text message is being sent to your phone and who is sending it.You can also transfer your entire phonebook from your iPhone to the main handset and it will propagate to all the other handsets in your home. The only issue I had with this was I ended up with 200 phone entries and found the search capabilities on the handset to be lacking. I erased all the entries and ended up manually entering the top 10 contacts I mostly dial.The build quality of these phones is excellent and though Panasonic has a newer model for 2024, I bought these for the DECT 6.0 capability which gives you more range and has better Amazon reviews than the newest cordless system.Anyone looking to save money and drop their landline service should be looking into this phone system. I had considered going VOIP but that requires a monthly subscription. With just your cell phone placed nearby, this entire cordless system will provide you with household phone access with no extra fees outside of your wireless phone plan. It's just short of being the perfect solution, and by that I mean there is a slight inconvenience in not having a dial tone or an immediate dial, but there is only a few seconds of delay to dial outbound. I also think the volume could be better, but it's good enough for these older ears to deal with.
