Review (5/5): Various use of grinder, but you’re a professional at all cost.
Yes, very professional.
I’ve put good use for my Acrylic Nail art.
Gives smooth results without rough end results.
Safe, it has various levels/volumes to go up and down from and control even with foot petal (it’s optional. Still works without it)
Has a switch on the back that you can change spinning direction.
