3 stars because I can not say that "I do not like" it does not take place, it is quiet, it does at least enable the circulation and extending the legs working a bit (I say well little) his muscles and abs. I'm not at all sporty, but - No effort required even with an intensity adjustment max. When you are at a minimum setting, pedaling in a vacuum. The intensity adjustment is really ridiculous, that even after adjusting the strap underneath the device. - The screen to count the calories km or lights but remains at zero is demotivating! - The delivery time is long compared to the average of purchases via Amazon, but it comes from Germany. The device is lightweight and to position themselves anywhere in or on the desktop. Because it is lightweight, it is not hyper stable but it is doable. On the floor, the sliding device, but you can put underneath a piece of anti slip mat (vynil end type sold in rolls). The advantage is that Office can answer the phone without getting winded, and not sweat ... and no aches!
