Having taken time to choose I opted for this product from a reputable brand. It is very ergonomic, cold cap (black section) allows a good grip to the loops. The materials are of quality. The clamp to catch the end of a farm wick well and therefore maintains good hair and then wrap. It's very easy to adjust the heat thanks to the + and - buttons and the screen. The temperature when the change varies in seconds. The heating time is fast (less than 1 minute). Small flat when switches off: you have a few minutes to cool completely and it is not known where to set pending. The loops are good. They have an average diameter if like me you have very long hair. I think that must be complete by cons with products in spray before and after styling if you like that they take a long time. 'Cause otherwise they go on a finger swipe. In short, it works I'm happy.
