Having used three pedal exercisers over the past year for total knee replacement surgeries on both knees, I can say without a doubt that the Ancheer pedal exerciser is the best available for my needs. A previous pedal exerciser was very good for several months. However, I pedal long and hard for knee strengthening and broke the medal flywheel on the unit! Tried to replace it with another product and that was a total waste of money. I've now had the Ancheer unit for about a month and this product is exactly what I need to regain agility, mobility, strength and stamina.The Ancheer pedal exerciser arrived as scheduled, was easy to assemble even for me (75 yr. old female) and works great for my home cycling between PT sessions at the rehab facility. I use it for 20 mins. at a time for about two or three sessions each day. And, it's easy to adjust the tension so you feel like you are getting a good workout. Yes, the unit is a little heavier (18 lbs.) than others I've had. But, that's what I like about it as it doesn't shift or move at all on the low pile rug where I use it. (For those who have commented about it being too heavy to move around, may I suggest that you find a location where it can stay put so either the senior or a family member doesn't have to move it back and forth.) The tension adjustment wheel is a little tight to turn, but that makes it secure for the actual tension you want to use. . .no shifting whatsoever. The pedals were easy to attach with the enclosed tool. I can't speak to any comments regarding switching the pedals from foot to hand types as I will only use it for feet so won't encounter any problems there. Also, I don't even use the pedal straps as the grid on the pedals is large, firm and deep enough that my slippers or shoes don't shift at all. As for the digital readout, that's not anything I can address either as I don't use it since I only cycle for timed sessions and a kitchen timer works just as well for my personal needs. I don't even have any batteries in the digital readout! Oh, and did I mention just how quiet. . .almost completely silent. . .the unit is?After going through two other pedal exercisers which were more affordable, I decided to splurge on the Ancheer unit and I'm so glad I did. It is well worth the higher cost for such a great floor unit pedal exerciser product. Give it a try and I think you will find it as great a buy for the price as I have.
