Impressed
I wasn't sure what to think of this when I saw it but I am glad I ordered it.  2 AAA batteries and simple assembly and we were well on our way.  I had some newer, not so dirty brushes, and some older, very dirty brushes.  I sprayed each with a little brush cleaner after filling the bowl about 1/2 way with warm water.  I was impressed at how well they were cleaned and they were virtually dry once I spun them for a few seconds out of the water.  This will now be my go to way to clean my brushes.  I gave it 4 stars because it does slow down considerably with larger brushes such as blush and powder brushes but it trucks on through.  I recommend it!
