This is a very initial impressions review. I bought this mostly because I get real antsy while I sit at my desk and I thought this would take the edge off.It does. I read once that people with adhd use these to help concentrate and I can see why. I am more alert and more engaged in whatever i'm doing. Like writing this review.I'm 63 and I definitely cannot use it under my desk. I have it set up a little in front of my desk and I use my gangly arms to reach my mouse and keyboard. Probably not very ergonomic but I don't really believe in all that posture stuff anyways.Tension is good. I exercise pretty moderately (walking, hiking) and tension 5 (out of 8) is a good workout.I have a rolling office chair on a hard floor so you can imagine that is a mess. I've pulled out a rug and I've taped up my chair's wheels. Still a hassle, but a stationary chair would probably be sufficient.It's heavy enough. It doesn't lift off the ground. It does slide on hard surfaces depending on how you pedal. It doesn't really slide on carpet.Overall, it is a good product. I'm not upset I can't use it under my desk because the description makes it pretty clear tall people might have trouble.If weight loss is your goal, which I mean who doesn't have that goal, I imagine 1+ hours a day over a long period of time (2-3 months) would shed pounds. In a way it's perfect for weight loss: very low cardio that you can do for hours. It's easy to forget you're pedaling.  Read Less
