I have a couple of different stands that I use for razor and brushes, and found that not all stands can accommodate the brushes. I currently have an omega brush loaded in this rack, hanging by the notch that is near the base of the handle and it works brilliantly. I can also load in other brushes that have no notch near the base, there probably is a brush out there that may not fit as easily but as it is made of silicone it should be able to hold onto your brush in some manner.
Razors no problem.
Also it hasn't moved off the mirror so stays put once in place give this two thumbs up.
