Query: Loud and cheap quality

Pros: It works for the most part.Cons: Like the other reviewers said, it's REALLY loud. The other main drawback is that the included nozzle heads are exceptionally low quality and just about useless. Please do not be tricked into thinking this is a good deal because of the "Accessory kit." Using the included accessories is an exercise in frustration.In summary, if you are willing to shell out more money for good quality accessories, this thing is mostly usable.
