Sunny Health & Fitness Magnetic Underdesk Elliptical, Portable Mini Standing Elliptical, Fully Assembled, Cardio Exerciser, Optional with Resistance Bands

I started using this the same day I received it. Other than popping the 2 AAA batteries into the LED readout, there is no assembly required. It's ready to use right out of the box. It's solidly built and is heavy, so it doesn't shift around, even when peddling as fast as I can on a polished wood floor. It has a low profile, which makes it perfect for my 27" (in height) desk and I'm short (5'1"). The elliptical motion is more forwards and backwards with a small delta in up and down motion, so if you have less clearance under your desk, it won't cause the issue I had with an under-desk bicycling exerciser. The bicycling pattern made me move my legs with a lot more up and down motion, which in turn caused my body to move side to side. This is not great when you are trying to type on your keyboard, or are in a video meeting. The magnetic resistance goes from almost no resistance to high resistance in 8 increments and is manually set using the big dial on the front of the unit. No dependence on being near an electrical outlet lets you exercise anywhere there's a flat surface big enough for it and something to sit on. This is not a model built for standing on. So far, it's everything I've been looking for - heavy, quiet, easy to use, low profiled, perfect resistance range, sturdy, and reasonably priced. I would definitely recommend this under-desk elliptical. NOTE: I bought this unit because my job is totally sedentary, and this was causing edema in my ankles. I've only been using the elliptical for 2 weeks, and the edema has lessened dramatically in that short a span of time. I'm expecting the edema to become a non-issue by the end of this month. Yay for staying in motion even when you're sitting at a desk all day long!

Excelente es un muy buen producto

I have Grade 4 chondromalacia and osteoarthritis in my right knee so outdoor sports are - by and large - out of reach for me. This little machine is great! I store it under my desk at home and either use it while I'm working or on my lunch break. It allows me to get regular exercise into my day and also helps rehab the knee. No complaints whatsoever, very happy with my purchase.

It's quite heavy but that means it's stable to use

My knee went on strike a few weeks ago, and I am trying to get strength back to go jogging. I bought this when my knee was too painful to bear weight on the elliptical at the gym. I’ve since graduated back using the standing elliptical & now just use this while working. It is too big for my desk at home, so I put it under the kitchen table. I find the resistance perfect for multi-tasking, but if you’re very athletic, the strongest resistance is not comparable to an electric machine. If this is for a senior or someone with injury, I think it’s great. Other reviews have valid points: 1) It is big for small spaces. It doesn’t fit under my desk at home. It might fit under my desk at work if I move my printer. 2) I have short legs, so it’s perfect for me, but I could see how someone with long legs would have to sit so far back, they couldn’t use the keyboard. 3) It is heavy if you have an injury or are older. When it first arrived, I was on crutches and moving it was…an ordeal. If you’re purchasing for a senior citizen, they can probably move it if they’re in good shape, but if they struggle with mobility, you’ll want to move it for them. 4) I do like there was no assembly, but I wish there was an option to remove the pedals for storage since I can’t leave it under my desk when not in use. I haven’t had it long, so I haven’t encountered issues with the battery. I find it’s quiet as advertised. Lastly, if you’re recovering from an injury, you can kick this up a notch by using weights and doing some upper body exercises while you pedal on the highest resistance. I was able to work up a bit of a sweat with weights, which was an okay substitute while my knee decided if it was retiring or coming back to work.
