Like many other testers I was doing a pleasure to receive this product and test it, but I was quite disappointed. Indeed no explanatory leaflet as if everyone was supposed to know innately how to use each of the accessories of this brush. Also trying to use some props I burned me several times and no doubt because I do not know how to use it: from where the need for full instructions included. The positive effect remained in the storage case but it is insufficient and it is not the purpose of this purchase. In short, a product review for Philips.
