No leaks
Works great on the 40 Oz circul bottles. They don't leak at all.

This is not an adaptor, it’s just a plastic screw on big jar opening.
If you insert a sip in this adapter, it will fall straight through. You still need a Cirkul sip sleeve. Terrible purchase I wish I could give it 0 stars

It’s great, but it’s stuck to my Stanley!
It definitely worked and turned my 40oz Stanley into a Cirkul cup. I wish I could get the thing off but oh well! I can still wash the cup fine since the hole is nice and big.

Where have you been my whole life?
I stumbled across these adapters while looking for something completely different. I had NO idea something like this existed! I have a bucket full of cirkul cartridges I haven't touched in over a year because the bottles are just so inconvenient for me-they don't stay cold long and are a pain to refil and clean. Enter this adapter...problems solved! Well, mostly. I do not have a stanley cup, but I have a few cheap dupes. This did not fit the cup I hoped it would-just a tad too small, but it did fit my blue one which is actually a cup I don't like and dont use because I hate its lid. Pop this puppy on, put in the cartridge and lid, and instantly I have a useful cup and a great way to get a lot of water, keep it cold, and have it flavored. I LOVE IT!It screws in at an odd place on my cup, but that was the issue I had with the cup in the first place so that isn't surprising and I don't think reflects with this product at all. It has a nice tight fit and doesn't leaks. And I have been drinking so much more water now that I can keep it cold all day long.

Not Dishwasher Safe
First and foremost, this does exactly what its supposed to do. It's an adapter to make a Stanley cup or a Cirkul Straw sipper work with a traditional Cirkul lid. The Cirkul Straw sipper doesn't really work, so this allows you to use that cup and tilt it like a normal bottle.The reason why its 4 stars and not 5 is that it shrunk in the dishwasher and was no longer usable after that.
