I love this thing!!! I'm writing this review using the TrekDesk. It took a bit of time to adjust to working and playing on my desk while walking, but not much. Now I'm playing Angry Birds while on the treadmill, and doing just as well as I do when sitting! I increase the incline and speed of the treadmill to get a good workout - when it doesn't matter that I perspire. I don't do that with my work clothes on. Right now the incline is at 5 and the speed is 1.5. If I had my work clothes on, I'd have the incline at 1 or 2. It's easy to be put off by the price, which is actually very reasonable for what you get. But keep in mind that if you use this regularly your health and functioning (physical, emotional, cognitive) will improve in many ways. And that will, among many other benefits, save you money you'd have to spend on doctor's appointments, etc. I truly believe this more than pays for itself with the health improvements you'll get. I felt motivated to buy it when I read that even people who exercise regularly, which I was doing, have health problems from being sedentary.
