Cons:
I regret that the caps can not be installed "upright" during their cooling. Indeed, the base is bevelled not realize what that action, hence risk of burns where you ask it. This is frankly a shame. Do not believe the pictures that present the brushes standing, you can not do it without you develop a base.
A storage bag could be offered with a naturally.
This big design flaw does not remove the product efficiency, it comes in to spoil the perfect pleasure. Good product overall, I recommend.
