I WILL BE BUYING one of these for my husband who has had lower back surgery! Now when its raining or Im watching sports, I can pedal away! Se ajusta perfectamente y es regulable gracias a sus correas. Really truly, the spin on this bar blew my mind, given the price. Didnt even come with the headband pads, which cost ~ $19. They are soooo comfortable! The charge lasts pretty decent. They are definitely not living up to their reputation. Screws that come with it are a little long for a cupboard door so I just used shorter ones that I had. They are kind of clunky but I enjoy them they are nice for work and around the house.
