Super Brush, frankly top quality, best brush I've tested, we see that it is the pro, has nothing to say at this level, blow drying is done in record time, like really well, and keep their hair beautiful volume and flexibility after it looks like we brush out of the hairdresser every day, nothing to do with supermarket brushes. I do not regret my purchase but to wonder why I have not dark earlier. I recommend a lot, myself I took a second different diameter.
