I too have managed to break some,when I catch the tubing on rails in front of windows or simply by adjusting the angle or changing the brush heads over, it's like they are too rigid if you know what I mean,if the plastic stem piece was a bit more softer or rubbery I can't see them breaking so easily,the kind lady at Gardiners posted out me a pair free of charge as the ones I ordered with my pole were too big,I really liked the new ones and shortly afterwards one broke so I bought another four just incase it happened again,I put my last one in yesterday but I'm afraid to use the brush now as it might happen again,maybe it's me and I'm too heavy handed,they seem to snap flush with the brush stock,I am very pleased with the spray they produce but for now I'm gone back to the blue Lumark fans on my other brushes,there not as good but at least I know they won't break.
Maybe I need to stop eating spinage
