Wonderful supplement to one’s daily exercise regimen
I spend too much time at my desk and even though I do get to the gym most days, I find it’s just not enough to keep the weight off. So why not utilize those idle hours to burn a few extra calories?After a bit of research, I settled on this model, the Sunny SF-E3872 under-desk elliptical. It is designed to be operated while seated; there are some other similar looking ellipticals that can be used from a standing position, but this one specifically warns against standing, so bear that in mind.It did take a bit of experimentation to get it positioned correctly. My particular desk is too low for my knees to operate the machine so it has to stick out a bit, and I have to sit back a bit from the desk. I finally put something behind the elliptical, wedged against the wall, and now the device juts out a little from under the desk and is just right.Meanwhile, I put rubber coasters under my office chair’s wheels, to try and stop it sliding back, but I do occasionally have to slide it forward again. I even attached a metal handle to the front of the desk, to have something to stabilize myself when exercising more vigorously.One other mod that came in handy: I attached a cheap LED rocker light just under the front of the desk, so I can quickly check the calorie display.When I first got this machine, I used all the defaults: medium difficulty, scan mode. The scan mode shifts every few seconds from speed to time to calories burned. If you long press the button, it resets everything to zero; I usually do that once a day. You can move it off scan mode by tapping the button, then keep it on time or calories which is what I prefer.It’s quiet. After 2-3 weeks, though, it started making a creaking sound, so I put a bit of 3-in-One household oil on each wheel, and it went back to being whisper-quiet. Also, I like to vacuum the area every couple of days, because of my obsessive-compulsive nature; don’t want a buildup of grit and stuff clogging the mechanism.Other than that…not much to say. I’ve been using it every day for about a month and it’s been great! I recommend it. If anything changes, I’ll modify this review but so far, steady as she goes.ONE YEAR UPDATE:Okay, not quite one year, more like 11 months! I’m still using this machine several times a week and it still works great. In fact I’m pedaling it right now as I type and it’s whisper-quiet.One improvement was to install casters with brakes on my office chair (it took a while to find good ones but Amazon came through!). Now, the chair stays put (almost too much so in fact so you have to literally lift the chair to move it) and this makes the elliptical easier to use with little distraction.I still oil it approximately every 3-4 weeks to keep it running quietly. It is still using its original battery, amazingly. I can still recommend this machine and if I am ever commuting to work again, I might get a second one for on site. And yes, I would still buy this one again. By the way, they have a couple of youtube videos explaining how to use which are worth viewing.

From Skeptic to Believer
Okay, I have to admit I always thought these under the desk machines were a gimmick. Well, I’ve been using mine for about a week, and what a difference for my knees and legs. Most of the cartilage is missing in both knees, and as a writer, I spend a lot of time at my desk, with its resultant lower leg and foot swelling. From the first day, this machine has changed everything. Because it’s strengthening the muscles around my knees, it’s like a miracle drug. I’d say the pain when walking is down by 90%. Every hour, I use this device for five minutes. There is less lower leg and foot swelling. Now, about the machine itself … it’s a solid piece of equipment. There’s heft in it. No bells & whistles to distract. It’s a professional-grade exercise machine. I’m so glad I bought it.

踏み込み式が重く且つ怖いという両親の足の筋肉を鍛えられる何か良い器具はないかと思い探していて、アメリカの高齢者が絶賛いているこちらにたどり着いた。結果、動かし方にコツがいるようで最初は全然動かせなかったが、慣れたら時間があれば動かしている。以前は歩き方がヨボヨボで心配になるぐらいだったが、ももの筋肉が付いたのか歩き方が遠目で見てわかるぐらい変化した。(本人曰く、膝の痛みも少なくなったらしい)　今後様子を見てemsなどにもチャレンジさせてみたい。

I love it. It arrived. It required zero set up. Extremely simple to use. Wireless. Reasonably priced. Very quiet. Up and running within minutes. No wires. It’s heavy, so it’s extremely stable on carpet. The batteries are included. It seems like solid piece of equipment and hopefully long-lasting. Note, the measurements are in miles, rather than km. Would argue it would probably be better not to use it with a chair that has a swivel back, (office chair) but i make do.
