They do a very good job of taking care of my eyebrows with a minimum of pain. Of course it's threading so there's still pain, but recently they changed the kind of thread they use and it was significantly less painful.
My only complaint is that come employees are slower than others and that causes me to feel each individual hair as it's being ripped out. But the shape is so much better than with waxing that I'm willing to put up with it.
