Good - but there are far less expensive alternatives that will work
This actually works really fantastically for cleaning makeup brushes - and is the only thing that will really get my Beauty Blender clean! - but I honestly have to knock off a star for the price. There's absolutely no reason this has to be as expensive as it is, as it's functionally no different than the ridged silicone oven mitts you can buy at the dollar store. Unless you're really trying to treat yourself or someone else, I'd say it's not necessary to buy this specific (expensive) product to achieve the same purpose - but at the same time, I can't deny it gets the job done.
