Simple, straightforward product. I recommend using the Color Switch mainly for smaller/eye brushes because you have more space to move around in with smaller brushes and can utilize every inch of the sponge before having to wash it. You can also flip the mesh and use the other side to extend time between washes, which is nice. The reason why I recommend using small/eye brushes is because wiith larger brushes, the entire sponge gets dirty faster, and I'd rather just spend less time washing the brush itself instead of the mesh sponge. Some people have made their own version of this for cheaper (can find instructions online, probably on Pinterest), but I didn't feel like I was wasting my money buying the full size one time because you can buy replacement inserts for cheaper, and I like that this comes in its own tin.
