Works fine. I tried it just once. I had some trouble finding the operation since there is just a small instruction paper in the package with adequate explanation. The machine must 'warm up' for a few seconds before starting. Anyway it seems decent. I have no clou if it is doing any work on skin improvement since I used it once.
LOOK GOOD, ALL MASK WORK BUT IT DOES NOT HAVE A SELF SHUT OFF TIME SO MASK WILL STAY ON UNTIL YOU TURN OFF.. INSTRUCTIONS ARE NOT IN ENGLISH.
