Bought this item via Amazon over other retailers because of the free shipping (delivered very quickly by Fed-Ex). Took a while to put together, and the tension chord was a complete bitch, but I broke out my trusty wrench and got it in place. This bike is very sturdy, and I tightened the piss out of the nuts and bolts so it would be. I can see where the base legs and seat may wobble if the bolts are not tight, so be vigilant about that. Had to get used to the smooth, noiseless ride, and the higher tension settings will get smoother as I get more used to it. The lower settings are very smooth and effortless. The plastic case was intact, no bolts were missing, all was good, and the bike fits into a convenient spot in my apartment and takes up little space. As a cardio exerciser, it works well, and after 15 minutes of use I was sweating like, well, like a fat guy on a bike. After 30 minutes I could barely walk, but, again, that's due to me, not the bike. The seat really does hurt the 'taint' area, but I'd chalk that up to my ass being too fat, and not as a fault of the seat. As of now, after one day's use, I am completely satisfied with this relatively cheap and very convenient (and silent) exercise bike. I recommend it, though I am no expert on exercise. Good value, solid structure, free and quick shipping = very satisfied.
