Query: Flimsy hardware

As some have stated before, the plastic adapter, that sits between the shower pipe coming out of the wall and the hose, is very flimsy. Mine cracked while installing it, part way through the first turn. I'm fortunate that the metal adapter from my non-filtered hand-help shower head had the same size connections, saved me the hassle of having to ship this one back.
