I have had one of these brushes before and was really pleased with it even on my shortish hair. However it doesn't have a very long life and despite only being used twice a week, it stopped rotating after a year or so.
I see there is a new model for short hair (32 mm barrel size) which I'm interested in.
Does anyone else have any other recommendations? I have shorter hair (2-3cm long) than before so I don't need anything with a bigger barrel but it's very thick and unruly and I found the Big Hair really helpful in managing it!
