I couldn't believe how easy and effective this system is. Reading all the steps it seems like some cumbersome process but I did compare my traditional shampoo on hand method with this swirl cup and there is no doubt about which one is better.
The textured cup makes all the difference in removing the gunk from the brushes. It is a lot gentler on the bristles, not to mention how much easier it is to then rinse the brush. No residues left, very fast to rinse out.
Perfectly clean brushes, in a fraction of the time, what else could I want? Luckily I already had lots of Brush Guard pieces, because I started to grab even the clean ones to wash.
One tip: if you go heavy on your eye make-up, buy an extra pack of the extremely small Brush Guards. It is important that you use a snug fit to maintain the shape of brushes.
