The chair was easy to assemble. The package had been rolled, but none of the parts were damaged. Simple straight forward instructions. The pump works well and fits in anyone's desk drawer for refill time. The chair is comfortable but may be a bit short for some people. My wife loves it.
I was positively surprised by the overall good quality of this machine, easy to assemble. It is relatively quiet when it vibrates which was my biggest concern, even if I don't use the speakers. It is also pretty stable. It has been working well so far but I have only used it for about 10 days 1-2 times a day without weight loss results yet but I do feel the muscle working. On what could be improved, the manual is very brief and not very useful, the plug does not hold well and the machine gets unplugged by just moving a bit, which is surprising because a typical,problem with large equipment. I am not sure why the calories loss is the same for all program levels when obviously the speed of vibration and the time is much dynamic as the program progress. I need to do some research.
