Funny.. I had a buddy of mine on IG try the same thing. It didn't work well at all, lol. He ended up getting one of these.. This company has a patent pending for a reason. They have tried all of the dollar store models and other options.. and then they made modifications from there. They fixed what didn't work and made their own brush.Yeah Betty Crocker in dollar stores for .99 cents. Same three flat bristle. I’ve tried a few and this one works very well. Gonna try to find again and have a couple in the cabinet.
