Contigo products are generally not the most cost effective bottles, but are often very well thought out designs that work great at what they do. These bottles originally worked as expected, but over the past couple months have become completely unreliable. The plastic coupler under the flip top no longer keeps the contents sealed in, as it just slips off the spout once folded shut. I could see if it happened to just one, so we discontinued the leaky one, and the next one had the same issue about two months in . Then the third will likely followed suit im assuming, and i will have thrown away my $$. Again, i have multiple other water bottles by Contigo of different design spouts, that have lasted years of daily use. I really expected more.
A:
Great for a while, then leaks like its left wide open.
