Good, last a long time.
I like the exchange system
Great idea, it's more ecological than always buying new brushes.
Great for replacing, pretty good quality, once had a brush head that wasn't all holes completely filled with brushes.
I've had it for years and am still satisfied
It's really great that these replaceable brushes are available. Much less waste, the handle lasts for many years and only the brush head needs to be replaced.
Perfect for retrofitting, therefore sustainable. Description on new packaging not complete compared to previous packaging.
super brushes
Good, too expensive
Practical
