these lids might be the best purchase from this website for me tbh! no more anxiety about ants in my drink. now, in terms of actually saving my couch from a spill, not really. it saved my bed once from water spilling bc I had just put on the lid and it was suctioned well but the second time it lost suction after an hour and my drink still spilled TT great for covering your drinks but i wouldn't rely on it for long term spill proofing!
Does a great job sealing your cup
Ive sent the link to this to a few co-workers its great for blocking anything getting in and keeping the drink warm for abit longer .
WORTH THE BUY !
This is a great concept but I need a much larger size for my coffee cups. Hopefully, larger sizes will be offered in the very near future.
