Review (5/5): Just buy it!
I was skeptical of this since it was much cheaper than others on Amazon and didn't have many reviews, but it sure surprised me! I use the ecotools brush shampoo and got through 2 dozen brushes in about 30 min, washing AND drying. I was worried it might not work as well on angled brushes, or any others not in a uniform shape, but NOPE, worked like a charm! I had some very thin handled brushes that were tapered at the end and didn't fit into any of these attachments, BUT, I used the smallest attachment that has the little slits in the sides and the brushes wedged in those little openings and were snug enough to work just like the others. Modern problems call for modern solutions lol One last thing is make sure you are using fresh batteries, at first I used some that were not new and it majorly affected the spin intensity. Fresh ones solved the problem. Buy it, you won't regret it, I don't see any need to purchase one of the many more expensive ones it there when this little guy works like a champ.
