I bought this unit for $499 (before taxes). I plugged in the unit to test it but then my husband bought me a laser hair removal package so I never used it. I decided to keep it for touch-ups but didn’t end up needing it for that use. It comes in the original box and all original guides and cord. Reasonable offers considered.
