Yesterday, as if everything is functioning correctly, my opinion aligns entirely with the description. It worked immediately, so I'm unsure yet how long it will function after charging. Overall impression is very positive; I recommend it.

Wow! I'm impressed! The toothbrush is excellent! Good quality!! Highly recommend!!! My teeth are even whiter!

Works, I have checked. As for the effectiveness, I still know. Fast Delivery

Very nice
