It is a small and convenient device to have with you. With daily use, the battery you will put in will need to be changed frequently. However, with a rechargeable one, there will be no issue. After weeks of use, there is a relative improvement in the overall surface of the face. Don't expect miracles obviously.

You don't see very dramatic results as it gives you the impression... But with continuous use, it gradually does the job

It does an incredible job! The only negative thing is the batteries, but if you use the same type as recommended by the company, there is no issue. Of course, it requires almost daily use for a week to see a difference, but it is truly worth it.
