I am auto mechanic for years. It is rare that belies the wiper arm, and leaves them just that time seized on the shaft. I tooling as Facom because tired of tools that break is the first use. But apart two arms in the year, I thought if I break not lose much tool. I disassembled a windscreen bay of a 308 to access more easily to the egr valve. I place the tool and greenhouse bed and I hear, I thought that the tool had sold well no! I have since dismantled three other arms and has not broken, if you consider the value for money, I think it is unbeatable. I was afraid that the rivets that serve broken axle, but even if he had broke, they are replaced quickly done well by screws / nuts. There.
