Review on Resistant Closure Sliding Replacement Tumbler by Tommy Rao

Tops don't fit well Elastic around the rim doesn't fit well or the top of the lid the part that should slide doesn't slide easily I understand it should be tight so its seals are good and won't have any liquid exit. Well the first one broke when being moved back and forth because it couldn't slide easily and the 45 degree part holding it in place broke off it was that hard to get it back and forth move. .I'm on the second one and it's hard to slip too, if this one breaks I won't buy from your site again. Thanks Mike Q
