it is ok [SEP] 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 is not such a resounding review but the various size rubber brush holders and all just are not necessary i do like the little round tank to clean them in though
