The brushes might fit the holder but they come flying out all the time. The bowl is left with an oily residue which takes a lot of effort to swill out. Only the very outer layer of the brush gets clean. There is still lots of product deep in the bristles. I get way better results from washing them by hand and with far less faffing about with the adapters and bowl arrangement.
