This headset gives cosmonaut look a bit funny but it is practical and effective. - Three temperature levels (for my part, I use the position 1, hot without excess) - Compact (it fits in a soft pouch supplied) - Saves time (with an extension cord, you can easily go about his business) - Makes it less tiring drying (no need to keep an arm in the air for a longer or shorter time) - Makes the hair soft and shiny (the heat is no longer an enemy, the hair is as beautiful as they dry in the open air, without having to wait 5 hours or more ...). I also used a few curlers (between two shampoos to give a little place in a few strands) and the result was just as satisfying, all the hair was soft). However, the announcement marks on the packaging that the headset is quiet, which is overkill (do not expect to watch TV or listen to the radio at the same time!), It's the only (minor) downside I him find. In summary, this small investment worth it!
