Good product, but not really for deep cleaning.
I'm happy with the purchase, as it dries my brushes in about 5 seconds flat. That said, it doesn't really deep clean, as I hand washed one of my brushes after washing it with this and was surprised by how much makeup had still been left behind. Also, some of my brushes have tapered handles, and the rubber attachments this comes with doesn't really work so well with them. Like I said, though, I'm happy with the purchase and I think this will work really well if you are doing in-between washes once a week or if you used a bold color and want to quickly surface-level clean the brush afterwards. It spins really quickly, though - awesome drying power!
