It's OK
I found I could dispense with all the bother of setting up the brush to clean using the battery device and just swish the brush in the cleaning solution and dry it on a paper towel.  Cleaning solution is expensive and after one swish the fluid was filthy and had to be dumped and replaced, otherwise I was just swishing the brush in dirty cleaning solution. Maybe my brush was really full of makeup and more frequent cleaning will save on solution-remains to be seen.  Sorry this isn't such a resounding review, but the various size rubber brush holders and all just aren't necessary.  I do like the little round tank to clean them in though.
