The brush is great. Packaging, shipping, and delivery are very good. It has three modes; the first two are just vibration of the bristles, and on the third mode, the heads move from top to bottom. There is a Philips for comparison, but this one is better, although it has its own cleaning method on the third mode. The brush is cool. Take it together with interchangeable heads, as separately it might be a fake. I recommend the seller.
