A hobbyist necessity. [SEP] Finding that I could really use a tool similar to a Dremel rotary machine but not as costly I chose this basically for the price.  It's simple and does what I need it to do.  Pleasantly surprised that so many different sizes of accessories are included.  My only complaint is the on/off switch; to power on one starts out at low speed, another click and you go to medium, once more to high, then once again to off.  A simple on/off switch would be better, but it's cheap and it does the job.  It is rechargeable (cannot replace battery) and charges through a USB adapter.  It's inexpensive enough that when it does fail it'll not pain me to simply toss it.  So far  I'm a happy hobbyist.
