I don't normally use elliptical machines because I prefer using a treadmill, but when I saw this at this price I knew I had to try it and also get it for my wife since she likes ellipticals.
Overall I think it's been a pretty great experience using this. The box was very compact and heavy but wasn't too hard to get down to the basement. Assembly took a little more than an hour, but wasn't too bad. It was pretty hard assembling by myself because there's a part where you have to hold one (very large/heavy) piece while sliding another piece into it, so that was a bit hard but overall it's not that bad and I was still able to do it by myself.
When I first tried to use this after I had assembled everything, it felt really wobbly for me and was not a great experience, but then I looked in the instructions and found the part where it says you need to level it using the included leveling pieces on the bottom feet part.
After leveling it the experience was dramatically improved and I noticed almost no wobbling or anything like that. I'm 6' 4" 276lbs, so I'm not a small person, so knowing it worked and didn't wobble hardly at all for someone my size is pretty amazing.
I'm going to be honest, I didn't really try using the app because it wasn't something I was interested in, I use an Apple Watch to track all my workouts and everything, so I didn't really need the app for anything.
Also, it was super easy to adjust the tension on this, and my wife and I were both able to use this easily with almost no adjustments, even though I'm 6' 4" and she's 5' 1".
Overall I'd give this a 10/10, definitely recommend, it's seriously a great elliptical at a very fair price and much more affordable than most everything else out there, plus it's very sturdy and easy to use as well.
