Review: Great help for my knee replacement rehab. - I ordered this after having a total knee replacement. It is perfect. It's light enough that I can lift it around myself, but heavy enough to be durable. I use every morning to make sure my new joint is in and still working right. I started at .5 miles and now up to 3 miles a day. I pull one of my rolling office chairs up to it. It was easy for my hubby to put together. It's very quiet, if on carpeting or a rug it doesn't slip. I feel like this has been a big part of my good recovery. It, along with my comfy chair has made my recovery so much faster and easier. It's super easy to use. It can also be placed on a table for shoulder recovery.
Review: Use real wrenches, toss the included ones - I just got this, so this initial review is based on assembly and first impressions. For reference I got the magnetic version that doesn't have to be plugged into an electrical outlet to operate. I read in the description of the plug-in version that it would stop after 30 minutes or so of continuous use, which won't work for me as I plan to use it for longer than that. First impressions are very good - the unit seems quite sturdy and well-made. There are very few parts to assemble - just the two "legs" and two pedals. It took less than 5 minutes to assemble, but more on that below. First impressions of the pedal action and resistance after assembly: I'm very pleasantly surprised. I intended to use this on light resistance for several hours every morning while working at my computer, and I was a bit worried I wouldn't be able to find the right level of resistance. This isn't the case - I find that my ideal setting is a few clicks from the highest setting, which leaves room either way for adjustment. I don't think I'll be able to build giant leg muscles with this machine - even the highest level is pretty tame, however for boosting my heart rate I think it's perfect. My goal was to replicate a somewhat brisk walking heart rate: mission accomplished. I'll edit my review after using the machine for a while. Regarding the assembly: Upon opening the package, I took one look at the provided "tools" and immediately threw them in the garbage. I used my own open-ended wrenches and adjustable crescent wrench for the largest nut with zero difficulty. I say zero difficulty because I READ THE DIRECTIONS. They clearly state you have to thread the LEFT pedal on COUNTER-clockwise. This is the opposite of how you'll try it without reading the instructions, and I believe this accounts for 99.9 percent of the difficulty other reviewers complain about. So if you have your own wrenches (13mm, 15mm, and a large adjustable/vise grip/channel-lock type), AND ARE WILLING TO READ the instructions, you will not have any trouble putting this thing together.

### ⭐⭐⭐⭐ Almost perfect -- but not quite.
*by Z***R on January 20, 2026*

First this is a great little exercise device for legs, arms, and shoulders. With crappy weather and the flu etc everywhere at the moment, I bought this to be able to do my basic gym workout at home and I can with it. Indeed (and i'm a senior citizen here) the 1 - 8 choices actually give me a leg workout I feel more than my typical gym visit. So why doesn't it have 5 stars from me. Because whether on my artificial hardwood floors or my area rugs, it moves and I have to stop several times to re-adjust -- definitely a pain. So I ordered a rubber mat, one with really good reviews, that will arrive in two days and we'll see. Anyone reading this with any hints how you have dealt with that issues, I'd appreciate knowing hints. Does a rubber mat do it for you? Maybe if summer ever comes around here again it will be better behaved on my deck (with artificial wood, too, so maybe not.)
