Replacement Lids Compatible with Stanley 40 oz Tumbler, Leak Proof Lid Replacement Fit for Stanley Cup 40oz, Spill Proof Covers for 40 oz Lid, (Clear, 2 Pack)

The lid my tumbler came with was only for a straw which I hated. I wanted a lid you can sip from without a straw and this lid is IT! It's leak proof, easy to clean, and really good quality. I love that it comes in a pack of 2 in case anything happens to the first one. The lid fits perfectly and I've already dropped my water bottle a few times and it's still in one piece, making this product durable ! Highly recommend to those who don't like drinking out of a straw all the time. I hated the original lid my tumbler came in.

Fit perfect

Fit perfect

I bought this because I hate built in straws and don’t trust that they can be cleaned properly no matter how hard you try! This was life saver and well forth the money! It fits perfectly and is of good quality in a sense that it is durable and very universal to many brands of cups! It is also from my experience universally leak proof and easy to put on and take off of any cup!

Very easy to use. Fits my tumbler with a screw top. The only negative is you can’t clean the slide top.

the Replacement Lids for Stanley 40 oz Tumblers as a backup, and while they worked fine at first, I ran into issues after a short period. Fit & Functionality: The lids fit the Stanley 40 oz tumbler snugly and are spill-proof when the tumbler is upright. The clear design makes it easy to see the drink level, and they’re easy to clean. Durability: Unfortunately, after a fall, the lids cracked and broke. They don’t seem very impact-resistant, so while they work fine under normal use, they don’t hold up well if dropped. Pros: ✔️ Compatible with Stanley 40 oz tumblers ✔️ Leak-proof under normal use ✔️ Clear design is convenient for monitoring contents Cons: ⚠️ Fragile — cracked easily after falling ⚠️ May not be durable for long-term heavy use Bottom line: These lids are okay as replacements if you handle them carefully, but they aren’t very durable. If you drop them, they’re likely to crack. Good for normal use, but manage expectations regarding longevity.

The way the screw in ridges are designed in this lid doesn’t allow it to properly line up with the Stanley cup in order to drink comfortably. The lid ends up way too close to the handle resulting in an awkward and uncomfortable hand position.

It’s okay but didn’t fit
