I try to cancel the order after read some review on this but Amazon send it anyway . this be a waste of time and money . the motor work when you turn it on but it do not vacuum anything . maybe it work on the molecular scale but do not clean up any dust on my keyboard or anything else . maybe this be a joke thing like a fake poo or split ink bottle ... for those of you that remember the `` Pet Rock '' , that be more practicle than this vacuum thing .
