Review (5/5): Good for the money.
I have been putting off getting one of these for a long time. I kind of wish I had done a little more research but for the cost I am happy with it.
Pros: It really works. Some of my thicker brushes need to be rubbed on the bottom of the bowl to help get them clean. A tip for really getting them clean - get them wet and apply your cleaner to the brush rubbing it in to get to the bottom bristles. Let them soak for a while. Then clean following the directions of the device. I did take a fish bowl shaped dish and rinsed them in hot water afterwards to remove the soap and extra residue. It includes a handy holder for the rubber pieces and device. Rechargeable!
Cons: Bigger brushes seem to bog it down a bit. However you just need to be aware of this and help it along. It would be nice if the holder included a spot for the bowl too. And it would be nice if the set came with two bowls and/or you could purchase a second one. And last but not least, I really feel like there should be one more size holder in the middle. I have a couple brushes that are right in the middle. I can force it into the smaller one, but feel like it will eventually deteriorate from such forceful use, and it doesn't stay in the bigger one. Maybe just one more size guys?
All in all, it does the job. I am rather happy with it and would recommend!
