They actually work quite well for 19t racing in the Komodo Dragon motor. I have been getting 5-6 runs minimum (usually more like 7) in 19t Foam Sedan before I feel like putting new ones in. This is great compared to most brushes that usually only last 1-2 runs before becoming burned. They theoretically could last 25-30 runs, but you have to keep in mind the brush gets shorter as you run it and you would have to increase your spring tension to return it back to the same amount when the brush was new. Also, a comm cut is generally required after 2 runs.
