Worth the Money
This is a very economical product which does most of what the more expensive models do. It also comes with 5 percussion attachments. The only negative comments:  1) The motor is not strong enough for much pressure to be applied; 2) The + and - buttons to change speed are located where they are easily accidentally adjusted during use, especially since they do not need to be pushed, but merely covered. With those things said, for under $40, this is well worth buying.
