It's great to have a brush that also blow dries my hair! It was a little confusing what the 3 settings actually do. Thankfully, the seller sent an email to explain: LOW--Cool Heat & High Air Speed MIDDLE--Warm Temp & Low Air Speed HIGH--Hot Temp & High Air Speed **Please note that the sign of settings indicates the heat and temperature, not the air speed. In other word, there are 3 level of heat and 2 blower speed. It is different from other hair dryer and it is easy for you to have a confused idea that settings are broke. If you encounter this confusion, please be eased. This helped to clear up the confusion. Good product!
Confusing settings but good drying brush
