The back wheel of the pins located at the end of the brush is not handy when you brush your own hair. In fact the withdrawal of the pins requires the use of both hands, one to hold the handle, the second to turn the wheel while your hair is wrapped around. In short, it is very sporty for medium length hair. The large size of the roll leaves also no room for doubt, one must have long hair so they can wrap around properly.
I also found the operation button 3 position not very ergonomic for small and slightly slippery.
This remains a quality brush that deserved a small storage pouch.
