- the product itself, the idea to make such a brush is cool. there is a gentle mode so as not to burn the hair
- 1. VERY inconvenient temperature and flow control, placed in the base of the brush - Rowenta engineers, what are you ?! you dry the strand with warm air, to fix it with cold air, you need to let go of the strand and use both hands to switch the mode - VERY INCONVENIENT. 2. cold air is not that cold - just not hot.
