It works better then expected.

When I first opened the box, I felt that it looks nothing like one $200 brush, the box is not sealed, the tag is attached casually, see the photo.
So, I didn't put much hope on it.
However, it does work. As for me it feels just like vibration, not something special. But It washes very clean, also it reliefs the Shaving discomfort, I don't know how.
It shut down a few times during using, I don't know if it is on purpose or I received a defective one.

So far, I like it. The only question is, if one willing to spend $200 for what it provides.

UPDATE:
I changed the stars from 4 to 5. I didn't expect it could do anything with my acne, however, it helps a lot. Unbelievable!

This works better then I expected it to. It took me longer to open the box, than to do the installation.

I really did not expect this product to perform as well as it does. The price was so low it just set my expectation low however this product works better than expected.
