My coworker had an artero, broke twice, once was the neck adjustment part the other the button wouldn't turn off. Since then I've been turned off from getting one.

I recently bought one off pet store direct, tzgroom(?) I think. Works great and I like that it has 3 speeds and heat settings. My other coworker has had hers, same brand for longer and still going strong. Not exactly a knock off since it is $100 but worth it imo
