Review on 💄 HENMI Makeup Brush Cleaner - Top-rated Electric Cleaning Tool with USB Charging, 2 Speeds, and 8 Rubber Collars for All Brush Sizes - Innovative Cosmetic Brush Spinner for Beauty Enthusiasts by Wanda Johns

I give this product only 2 stars for several reasons: 1) Cheap design 2) Works mostly with lighter brushes. Heavier brushes tend to slow the motor even at high speeds. 3) Definitely doesn't work with flat and small brushes. 4) The rubber brush adapter allows the brush to swing sideways, especially at low speed. Cons: 1) It comes with a rechargeable battery 2) The bottom of the water cup has various grooves instead of a flat surface that help with makeup removal (see image) 3) Makes the brushes almost dry after cleaning Most brushes. Noticing that my brushes weren't cleaning thoroughly, I ended up sending them back and resorting to hand washing.
