I spend hours at my desk working and playing on my computer every day. This product was exactly what I was looking for to add a little more exercise in my life. It is sturdy and fits under my desk nicely. However, I had to remove the bottom keyboard pull-out drawer from my desk so that I don't bump my knees while using this product. The resistance works great. I can make it as easy or hard to peddle as I want. However, if you go backwards, it doesn't keep the resistance so it is probably not meant to be used backwards (although after using it for a while, it feels good to peddle backwards). This thing was pretty expensive, but after how much I've been using it while at my computer, it was well worth it. It seems like it will last a long time. When it is not in use, I just leave it in place under my desk because it does not take up much room at all. Also the electronic clock/counter is not needed at all (calories counted, rotations, etc). You will also notice that this model does not have a peddle strap because it is not needed. I can peddle away with socks or shoes and not slip.
