Can anyone share their experience with a good quality professional Ultrasonic Skin Scrubber? I have had a Skinmate  which has served me well, but it was purchased years ago and it's time for a new one.

I have tried the Skin Spatula with 6PZT ceramic crystals in the hand-piece, but clients has not enjoyed the high pitch sounds and it get too hot to use for extractions. I have also tried the small cordless 2PZT unit and that works fine for the extractions, but I would like all features…
