This rather impressive at first glance brush for those like me who used small round heads is very convenient to use, instead of 4 passages they do not make more than 2, all of the hair is brushed gently, I disentangled more easily. For long hair is great for short move to a smaller model. The wood is solid light bamboo and environmentally friendly, the pins are secure in the air bearing that seems solid. To see in a few years.
