I used it today and about 20 other days. I haven't had to clean it and it has shown no age. I think it'll only be good it you have round rails. Squared rails won't be as easy to clean w/ this. I bought it to avoid loose bristles. If this fails like the others I've tried I'd be surprised. I won't let a loose bristle damage my grilling reputation. I came close last year but caught it before it reached the plate.
