The treatment was fine, but I don't appreciate several phone calls to be hustled along to an appointment I have booked and paid for at a time I have chosen for my convenience. If 8:15pm isn't good, then don't open that late.
So I'm not a fan of the roll-on wax appliances because I don't think they are as hygienic as a spatula that isn't double dipped. That being said, the service was thorough and relatively painless.
