Pole connection broke at thread end the first day I used it. The plastic male thread end which connects to a broom is poorly designed – it has sharp corners which cause stress concentrations. Also poorly manufactured – the cast plastic thread had a large interior bubble at the thread root (not visible from outside). Strong pole is of no use if the threaded connector is the weak link. I replaced it with a wooden pole that has a cast metal thread – no problems with that to-date!
