Meh product.
Single charge only lasted me 2 usages. Should have a more lasting battery life. The material feels cheap as it is plastic. For this price range, I would expect a more substantial material like metal as it feels more solid and lasting. 1 common button for on/off and changing of lights, so I presume the buttons won’t be lasting as well due to frequent pressing of the buttons. Definitely not for this price range. Used only 2 days, yet to see any effects on skin.
