ok, i love my mini novas in everyway. they are just about perfect, just about everything i could ask for in one of these devices. BUT after using mine for a few days, they base starts to separate from the housing, leaving the center part crooked allowing all the juice to be directly sucked into my mouth... not fun when im at work in the wilderness miles from anything and of course it happened the worse the one day i ran out of water, and could not rinse my mouth out... blech. now i pay attention and just tighten it down before i use it but i need to figure out how to fix it. should i use epoxy or something? i have already had a few problems with this order and do not want to go through the exchange process again, i just want to figure out a way to fix it my self.. any advice?
