Spill-Proof Silicone Accessory Set for Stanley Cups - Includes Straw Covers, Round and Square Leak Stoppers - Anti-Dust Tumbler Accessories

Thank you for my order, this works good on drink cup,make it spill proved,

Pros: Affordable Does exactly what it says it does Comes with a cute lil container to store the extra pieces Cons: No instructions , design is intuitive but a reference would be helpful The circle stopper fell off twice after putting it on - however it did not cause leakage Overall happy with this product but annoyed that the cup didn't come with these features already.

My daughter and I were disappointed with how much the Stanley cups leak. These nicely fit stoppers truly helps! My daughters 40oz doesn't leak at all, my 30 oz does maybe a driplet. Honestly, I'm nervous of tipping it over like my daughter does hers all willy nilly. I like the simplicity of the rubber and the top stopper seems like it can handle alot of putting and pulling off. Great product, great price.

The straw insert works well to eliminate the gap for water to spill around the straw. The round insert under the cap doesn’t stay on and it’s tough to drink out of with the air flow restricted. I tried putting a few holes in it but it still falls off into my mug.

These are perfect and they work. They work a little too good and I can't grab them out with my small fingers. I make my boyfriend take them out before washing. But this thing is seriously waterproof. If you drop it in the car and it rolls on the ground, it ain't spilling! Carrying way too much and your drink is tilted to the side? It ain't spilling! Only minor nuisance is when you're washing the little pieces and you might not find where you put them to dry. For the longest time I could not figure out where that big circle piece goes but it goes in the middle on the bottom of the lid.

Is not spill proof entirely. It definitely releases spills slower than without but doesn’t completely stop it from spilling

Was a little complicated to put together but it’s good not completely spill proof but will only drop a few drops of water if tilted over

Don’t bother. The inside stopper falls off. The insert for the straw falls in.

Arrived quickly, and worked well! Yay, no spills!!

Not good
