Review on Masterson Rinse Well: The Ultimate Solution for Cleaning Paint and Craft Brushes with Fresh Water by Karla Richter

Not a fan. I bought this for makeup use as it was highly recommended by another makeup artist. The brush rinse stain is so shallow and small that I had to rinse the water off after each face painted to keep the water looking decent, which means it spills out pretty quickly. When you flush it, new water comes in at the same time as the old water comes out. So when they mix, some of the new water merges with the old and some of the old stays with the new and yours. Water is never clean. I ended up going back to my two-cup system: one for removing most of the paint, and one for the final rinse. This system keeps my brushes clean, and if you need to change the water, I'll start with a clean slate. Great idea, but there are some real downsides.
