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

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.

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.

It’s perfect, it did spill a little bit but it’s pretty vacuum sealed, I was tired of my Stanley spilling in my bag, after using it today it didn’t spilled in my bag and I’m happy about it. Other stuff the middle part that everybody talks about that it falls, it’s doest falls on mine ? I do recommend it c

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

The straw covers are great. The other two items are absolutely worthless. The round cover only fits certain cups apparently, and not the ones I have... The part that's supposed to go around the straw falls out every time you try to put the straw in it. I have a name brand set and they are very much better. But the straw covers work, so there's that.

Every time when I refilled my water and drank out of it from the straw , the middle round part always came off and dropped inside my water. I don’t know why really. I thought I didn’t put it in the right way, but it happened so many times after I put it back in and it came off again. The straw part was excellent it didn’t leak at all, but that middle part is bothering me.

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
