As a washer, it is perfect.
After using it, I can see the whiteheads both on my husband's and my nose have gone. The pores also get less obvious. Now I barely use any facial scrub product.
The result could be quite dry, so I use it only 2 times every week and sometimes when my skin gets very dry due to the weather, I use only once. I put it in lower speed usually and use it with Benefit facial washer.
The battery length is quite crazy as, since August 2017, I haven't charged it for the second time (2 people in the house are using it). It is a great advantage for traveler and wire-phobia.
On the other hand, the back side for massaging the face, really not very impressive. I have to put lots of product on face to minimize the fraction when I move the device, and while I put lot of cream/oil, the device becomes very greasy. I used the side for 2 months and felt it's not any different from my own hands, so I barely use this function now.
