Query: **LIDS BREAK**

I like this travel mug for the fact that it doesn't leak. HOWEVER I have now bought 5 mugs because the lids keep breaking. The button/lock mechanism breaks. Or the attachment at the hinge that is supposed to make the lid bounce back breaks. None of these instances have been the result of dropping the mug. They just break at random. Very poor design for the lids. The Thermos water bottle which is fairly similar in design has never broken once. I've had those for years! Why can't you just use the same design????
