Really like these mugs for their purpose and would give them 5 stars but one of them has started leaking water from the handle assume it has taken in water from the dishwasher

The only reason i didnt give this a 5 star is that the seal on the lid is not tight

It doesnt leak while drinking but the top on my cup popped off on my desk i hit it with my hand and my finger flipped it up and the coffee spilled all over the place

Even with daily washing it still stuck underneath and when i gently pulled it up to try to clean out what was squishing out from under it the thing popped off

I initially thought that it was a clip together and it was supposed to do that so that you could get under there and clean it but come to find out that is is lightly glued together and not intended to come apart

I am going to attempt to reglue it and see if it works again but that still doesnt solve the problem of cleaning under the slider

It is perfect but the mug i received didnt have a mountain on the side when the picture on amazon had a mountain
