Never tried it myself, but EVERY single report I've ever read about these "RF tweezer devices" says they do NOT work.
IMHO, the only home units that DO work are galvanic devices that use needles which penetrate the pore down to the follicle such as the Iverness OneTouch. I can personally attest to this, though it takes FOREVER to use, and it's almost impossible to do yourself. But the patches my wife cleared on me did NOT come back, even after a number of years.
