Review (1/5): Wow!  Don't Buy This!
Edit May 16, 2019: I just sent the second brush cleaning machine back to Amazon for a refund. The first unit I had stopped working not long after writing this review. It just stopped working. It would not charge. I sent it back and decided to give the product a second chance. The same thing happened. And before it died, after the first use, it held the charge for a shorter time, each time. After fully charging it would die after cleaning maybe five brushes. I'd rather use a brush cleaner that takes batteries. I am going to get some rechargeable batteries and shop for a new cleaner not made by this company!! I have had a similar makeup brush cleaner but I think the motor may be going on it and one of the rubber attachments is tearing and it eats batteries like crazy, so I decided to get this one. Oh wow! My other one had one speed and this has three. The highest setting is crazy, in a good way. It dries brushes so fast; less than 10 seconds easily. The attachments handle all my face and eye brushes without a problem: even the ones with oddly shaped handles. There's only one brush that it doesn't do well with, which is a large, thick facial fan brush. The brush shampoo I used was ecotools shampoo. You just need a drop in the water bowl. If you add more you'll have the bowl overflowing in foam. It also did all my brushes (a lot) without running out of power on me and it charges quickly via the USB port. Yeah, no more going through all those batteries!
