Review (5/5): Revised Review
Thanks to both Amazon customer service (and Deborah) I am updating my review to FIVE STARS because it is a GREAT little machine once you finally figure out exactly HOW to use it!
There SHOULD BE instructions on the drill bits and their use, instead of having to go back to the Amazon advert to find that information!
The air cooling system and pink dust blockers are my favorite things about this machine, including the fluffy nail dust brush.
It IS an excellent product, the Seller just needs to be more specific. You have to hear the loud "click" (I don't know what "KA" means) to know that it's unlocked, then insert the drill bit, and then turn it completely back to the "S" position, then you're good to go from there!
