Query: inadequate adhesive

This product's design relies entirely on a piece of double-sided adhesive to attach the latch hook to the toilet bowl rim. The adhesive simply isn't strong enough to do the job. It *is* difficult to open the toilet lid by opening the latch (as it should be: that's the whole idea), but this merely encourages the user to easily rip the entire latch and hook off the toilet rim. Once the adhesive has been ripped off the rim, the adhesive has lost much of its sticking power: you've got yourself a piece of plastic junk.
