Review on Tumbler Lid - Yeti Rambler/Tumbler Compatible - Spillproof Replacement for Ozark Trail Lids - Magnetic Slider Cover - Black, 10/20oz, 2Pcs by Chris Estes

Availability **Update: I have contacted the seller and the seller has stated that the caps are not fully sealed but only minimize leakage which means they leak a little. So do what you want with this information. I wish they would say before buying they still have a little licking. I will return them. First review: I tested both lids I received and both were not airtight. The water kept dripping when turned upside down. I asked the seller if I just have faulty lids or if the lids aren't completely leakproof do they just minimize the amount of leakage? I'm happy to change my review to an answer/get a replacement.
