Based on the price, one would assume that they're another no-name chinese, but he swears up and down that they're top quality and lots of people at MA and club level buy them and love them... "These are Pro Level 200 Series Tire Warmers, We developed them for use on the big Dunlop 200 Race Slicks, they go across the full tire tread surface area and come with Deep Side walls to contain and drive heat all the way to the rims.
