2Pcs leakproof lid replacement for Stanley Cup 40oz (1.2L) - Clear Replacement Lids Fit for Stanley Travel Tumbler 1.2L/40oz - Spill Proof Tumbler Covers for Stanley Cup Accessories

These particular ones are an exact fit for both the Original Stanley Quencher and also the almost identical B&M flask at £4.50. Thoroughly checked, and can assure you that neither of them leak. These replacement lids are much better than the originals, which to be honest are completely useless, as they both leak a lot !! Just cant understand why the original lids are supplied like that with a hole for a straw !!Anyway, I can carry it in a bag now, and not worry about leakage. 👍. Great product. 👌

Doesn’t leak at all like the original straw lid, soo good!!! Only thing is the colour of the lid is a bit lighter than my Stanley colour but still cute.

The straw function does not work , yes it’s leak proof but you cannot drink water using the straw making it completely pointless

Great, it finally made the Stanley cup useful

Great lid for my cup. It's not a Stanley, but it has the same dimensions; this lid fits perfectly and is great for stopping the cup from leaking when it falls over.

The lid fits perfectly on my Stanley cup! No leakage at all!

This review is for the “2Pcs leakproof lid replacement for Stanley Cup 40oz (1.2L) - Clear Replacement Lids Fit for Stanley Travel Tumbler 1.2L/40oz - Spill Proof Tumbler Covers for Stanley Cup Accessories”Product efficacy: I love this lid because it does not leak, unlike the original lid. I particularly like that I can flip up the straw and fold it away as and when I need it. It does take some time to screw it on properly as it doesn’t always sit flat. You get two in a pack which is great if you need two or one spare.Value for money? For just under £9 I think these are well-priced. I recommend them.

Straw does not fit in the lid, makes an awful sound when drinking and just overall isn’t as described
