Sunny Health & Fitness Flip & Foldable Rowing Machine for Home w/Extended Slide Rail, Full-Body Workout, Low-Impact, Optional Extra Long Rail, Quiet Rail Cover, Water Motion and Free SunnyFit App

I'm no expert but it works for me. You'll need a mat if it's going to be on a smooth surface. The display is virtually worthless.; you're better off using some other means to time and track your activity. Assembly was easy. It was packed securely, so unboxing was tedious. The wheel unit, as you would expect, is fairly heavy. Some will need help with assembly. Great value for the price. Recommended.

Truly love this rowing machine! Was surprised at how easy it was to assemble - just a few hiccups and I was able to use it the same morning I finished assembling. What makes this great is the SunnyFit app - I love being able to watch rowing videos from around the world. Makes the workout so much better!

Why did you pick this product vs others?:I picked this brand over others because it offered a free app for Android. Turns out, the app isn't compatible with any of the THREE Android devices I own.I contacted their Customer Service, and they told me there was nothing they could do. They can't even give me an estimate for when the app will be available for any of my devices. Save yourself the trouble and download the app BEFORE you buy to make sure your device is one of the small number they support.As for the rower itself, it's quite basic. It works well, although the handle feels a bit on the low side (and I'm pretty short).  The plastic roller under the seat is slowly shredding itself, leaving small plastic shavings over the rail so that I have to wipe it down regularly.  Other than that I have no complaints.

I enjoy this better than the concept 2 machines I use in gyms. In fact, now that I have this, I'm done with the hassle of gym workouts.I bought the RW522016, which is the slightly upgraded model from the base model, so I don't know what the base model would be like. One of my reasons for paying a little more is that the rowing machine is going directly above the bedroom of our downstairs neighbor's 4-year-old son and we wanted to go for the quietest machine possible. That is what we got! This rower is silent. I would have no hesitation using this in the middle of the night. You cannot hear it 6 feet away.Assembly: I had some trouble finding the instructions--would have helped to have a QR code on the box--and then the ones I found didn't match the glide rail I had on step 3. But I called customer support and with 0 wait time got a super-competent American support person who walked me through the last half of assembly. One important pointer she gave me, which isn't in the manual, is the lift up the glide rail in order to insert it during assembly. In the end, I was missing a spring washer for the computer hinge, but there was an extra flat washer and I used that instead since it's not a moving part. Altogether, assembly took about 45 minutes.Exercising: Some reviews complain about not enough resistance, but I would dismiss those concerns. For me, a moderately fit 60+ year old, this has plenty of resistance and I feel an arm/shoulder workout within a minute at the 4/8 setting. But my hyper-fit wife also finds herself not needing to max out the resistance. Like I said, this machine is smooth and almost totally silent. The computer measures a lot of stuff, but since it's not using personalized data like weight and so forth, most of the stats are hypothetical. There is a separate holder for a phone or tablet, so you can watch your stats and your videos at the same time. Time flies when you are looking at 2 screens. The ergonomics are good, with no conflict between footrests and handlebar trajectory.Storage: I use this in a small room that doubles as a study and a nap-room. So it has to foldable, easy to set up and put away and more or less unobtrusive. Folding involves removing a pin and loosening and removing a knob that holds the rail level where it inserts into the body of the rower. It's not the most sophisticated system, but it works and it fairly quick. Once the rail is folded up, it can be tilted and wheeled into or out of its storage location. For me, at 5'11", it is easy to move this. it's a bit harder to leverage for my wife, at 5'5", but she manages. As you can see from the photo, we store it with the rail against the wall for aesthetic, safety and space-saving reasons. This involves not just lowering the rail to use it, but moving the rower out and turning it around in the space. It's easy enough.

It is a nice enough machine for the money, but after 1.5 years the rowing mechanism fell apart. This machine was not used every day, but one day I was using it and heard something break and parts falling inside the machine. I will not be buying it again.
