so far so good. be cautious of the cords plugged from chair to computer for lights and massager so kid dont trip over them and pull them out. works great and kids seem to like it. I sat in it for awhile with the vibrations on and I was liking it. There is one issue that could cause a problem for some... the chair is quite narrow. Im 54 120lbs and my kids are all thin as well. My husband is a bit bigger and he cant fit in it at all. Im pretty small and even I can see how this chair needs more width for average person.
