Query: Disappointing

For a company with a good reputation, I'm very disappointed in Waterpik. The large showerhead is quite heavy and the gooseneck can barely support its weight, so unless you can mount it fairly high up on the wall, the showerhead won't stay at a proper horizontal angle. Or it will stay up for a while, then slowly sag. It has recently developed an annoying whistle; those holes are tiny, so they are probably clogged, but how does one clean this unit since it doesn't come apart? Stay away from this one, and buy something else.
