Love this thing, it works! Easy to install and your Stanley won't spill anymore. I did have to poke a tiny hole in it because the seal was TOO good and sucking on the straw was harder. Still works perfectly!

Bought these for my cute new Barbie Stanley that I want to carry around with me everywhere. But my Stanley kept spilling from my clutsy-ness. I thought these might help a little. But they help a lot!!! My Stanley isn’t spilling. And it still looks cute. The only difference is that when you go to sip from the straw, you have to sip a little harder. The water doesn’t suck up as easily. But I can do that. And it’s worth it.

It was easy to install following the included instructions. However, mine leaks and I had to read the FAQs to find out that it does not work with hot or warm water/ tea.

If you install all the pieces of this set on a Stanley 32 oz tumbler, the seals are so tight that you can't drink; it creates an airlock / vacuum and no fluid moves up the straw.We took off the round seal on the bottom and only use the straw cap and the straw opening cover that goes on top. In our setup, some fluid may leak out from where the pivot cover inserts, because we did not install that leak cover part underneath. Works well enough for our daily needs. It slows the leak process down enough that I can usually set the cup back up before the fluid gets out or with a tiny amount of fluid leaking. Definitely better than not using the set.I really like the set. I love the color. Straw cap perfect. My husband and I each have one. Colors are great and don't fade. The silicone feels nice and soft to the touch. Fits well with the plasric straw set we bought. Thick but flexible attachment parts that seem like they will last a long time. Enough quantity for spares or multiple cups. Easy to take off and on to clean.Took off 1 star because:1. You can't drink from the Stanley tumbler when all the leak proof components are installed.2. The twist part of the top gets stuck on the leak proof insert when sliding the top to close the sip/straw opening. I have to lift the stanley twist part up a little to get it up and over the edge of the leak proof insert.I am happy with the purchase even though I think there are opportunities for the vendor to improve the product.

After searching all my neighbors I found my package in their porch , but for the review of the product 5 stars. I have the 40oz 2.0 Glinda Stanley for reference , I added the peices and flipped the cup over. It leaked , then I read the instructions and found that I put the little square piece under the cop instead of installing on top like the instruction's show. Worked ! And worked well. I held the full cup upside down and moved it quite a bit , I also knocked it down . It doesn’t leak. So happy I can keep this in my car , backpack etc now . When it falls over at the gym it will not leak either . You also get 4 sets of these in a little case . Worth every Penney of 8 bucks lol . Buy it .

Everyone loves a Stanley but if you hate how it leaks get this set. The Stanley totally doesn't leak I'm shocked that it really works. Fits both the 30 and 40 oz Stanleys that we have. Easy to install, easy to put on and remove to clean. Happy Drinking - Stay hydrated and Dry!

I hated carrying my Stanley in my bag during my walk to the office. It ALWAYS tops over and spills my water inside. I researched this product and the reviews, and it works PERFECTLY! No spilling even when I turn it upside down. I love it!!!!
