I bought these because I was sick and tired of knocking my Stanley over and it spilling everywhere. After putting these on I could honestly throw it across the room and it wouldn’t spill a drop. The color matches perfect and it was all fairly easy to put on as well. I will definitely purchase again and recommend to anyone that wants a leakproof Stanley!

Happy with set, but too leakproof for Stanley tumblers

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.
