Review (2/5): I wanted to like it, but it broke.
I really wanted to like this product, but if failed. The issue I had was with the spindle, it attaches to the main body, you then attach a collar (what the makeup brush fits into) to the spindle. You are given multiple rubber collars to insert your differnt size brushes into, then you attach to the spindle. Some brushes are too big for one collar, and too small for the next size. I found cleaning the brushes was okay, larger brushes barely spin. You would think since they fit into the large rubber collar it would work, but like I mentioned it barely would spin. After attaching and detaching several brush collars, the spindle would not stay attached to the base unit. I tried several times to fix the device. The spindle is like a drill bit that needs to be attached to the main unit, and it holds the rubber collars which hold the brush. There was no way for me to keep the spindle attached, so the piece became useless after cleaning six brushes. Conceptually, this is a great idea, but I think the unit needs to be a little sturider and they need to find away to allow consumers the ability to reattach the spindle. If you use large powder brushes, this unit barely spins them. It worked great from smaller brushes.
