Review (4/5): Works with some exceptions
This works as avertised. It’s quite hard to push the brush inside the silicone tube holder but once you find the right size, it works. Make sure that the fit is very snug though, or else it will spin unevenly from side to side and ruin your brush. The bowl is sturdy, however, the bowl’s edge is quite sharp. The instruction says to take off the rubber collar and wash both the bowl and collar separately. I find the sharp bowl opening to be quite dangerous.
Also note that you can’t wash double-ended brushes with this. You cant wash flat end brush either.
