Review (4/5): really cool idea
i've been excited to get one of these for a while. i'd definitely recommend it to friends, however there are a few things i wish were different.
1. i think it could spin faster/harder. i found that i had to use this tool, then run my brushes under the faucet and clean out the center of the brush myself, and then do it again in order for the brush to come truly clean.
2. some of my brushes are double-ended. i think it'd be nice if there were an attachment that could hold double-ended brushes. i made it work by finagling it a little, but it'd be nice if it were already equipped.
