Not strong enough to handle normal treatment being banged around while loading and unloading. Didn't last a full round. If someone puts their bag beside yours in the cart and makes contact, it will break.

This product has the right idea, but is too hard to use, First of all it should have a stretch coil attachment so it doesn't have to be unhooked and re hooked every time it's used. Secondly its takes considerable effort to squeeze some liquid out on the brush. Far too much effort than need be, so much so that some won't be able to do it. It should have multiple holes to the brush to make it easier and more efficient. Bristles should be shorter and stiffer to be effective on golf club irons. For what you get I think it is over priced
