OP - in answer to your question - no! this has not happened to mine, the aqua daptor is a very well made item, the only thing i have had go wrong is a snapped spring, which was replaced extremly quickly. overall the aqua daptor has outlasted in line taps and remotes ! so no complaints.
not to knock the OP but there is some serious and 'dubious' dents in the aqua daptor shown that look very simular
to marks left by mole grips or pipe pliers.
With any manufactured item there will always be the odd failure due to a flaw in material, bad machining, or simply put together on a friday afternoon!
this does not make it a bad or untested product
