Jmoe USA Bottle Adapter Compatible with Yeti to Cirkul | BPA Free Plastic, Food Grade Silicone | Fits 12, 18, 26, 36, 46, 64 oz YETI Rambler Bottles

Original post - Bought this to fit the 26 oz yeti bottle. It fits the bottle well with no leaks however it does leak between the adapter and the Cirkul lid. Tried several different lids just to make sure. All of them leak. Giving it a 3 because I didn’t contact customer service. I decided the yeti bottle was too heavy and went back to the Cirkul bottle.Update - I was contacted via Amazon by customer service. They refunded my money (not requested by me) and sent a new adapter, which I did request. After using the new adapter through six full bottles and two different sips I am pleased to say there are no leaks and this product works as promised. I am using it with the 26 oz yeti bottle.A++ to this company taking the initiative and standing behind their product. I highly recommend this adapter if you prefer cold drinking water.

Adapter works fine - fits onto yeti rambler bottle. The gasket is a lot more loose than it should be - having a more solid O ring around the top of the threads I feel would work better. I'm constantly having to fix the positioning of the current gasket and sometimes it bunches up when I'm tightening it down.Also lately I've been getting leaks from the Cirkul side of the adapter.UPDATE: Seller has contacted me offering a refund/replacement for my issues. For seller responsiveness I am upping this from a 3 to a 4 star. Too many sellers don't back their products well enough to reach out and make things right.

It fits well for the bottle to the adapter side but does leak a little from the cirkul lid side so when I tip it to drink I do get water down my shirt a little. Not enough of an issue to get me to not use it though. Other than that works well.Update!: customer service reached out to me, gave me a full refund and sent me a new lid and this lid does not leak. I am very happy with customer service and the product.

The seal doesn't fit tightly, like others have noted it slips down because it's not tight enough and needs to be a tiny bit smaller as well as a little thicker, I don't know why the company has failed to address this issue. I may have to go looking for a seal. I did try the one from my Rambler, while I can get it on, it doesn't stay in place because the area on the adapter for the seal is not wide enough for the Rambler's actual seal to stay in place.

The adapter is so good when it works but is so disappointing when it leaks. I've found that it helps if you wipe the threads and the cap completely, but there's still like a 90% it will leak at some point before having to refill it. The cirkul lid will also sometimes just loosen out of nowhere and I found that out when I tried to pick up the bottle by the lid and it fell off and water exploded all over my car. I ultimately think the threads are uneven on the cirkul cap part of the adapter making the o-ring to not fully seal which allows water to get out from the bottle. I want this to be better but as it stands I have a water bottle that leaks and that I can't carry by the carrying handle on the lid for fear that it will slip off the bottle and dump water everywhere.

This was a game changer! I love my SS Yeti and I love my Cirkul. But my Yeti keeps water SO cold! This adapter lid has changed my entire drink game. No joke! I was skeptical. But I’ve used it for about 2 months now. No leaks at either seal and it fits perfectly. Highly recommend this!

I had a tiny issue where part of the thread seemed to be slipping, but I contacted the seller and they had a replacement to me very quick! The newest one works a treat!

Unfortunately I love this idea, adapter fits the yeti rambler threads nicely and has a gasket. That being said, the top part of the adapter does not match properly to the cirkul tops that hold the flavor pieces...kinda important 😤 if you try to tighten it, it crossthreads and pops right off,or if you pull up a little on the cirkul pop top, it can pop the tiny but of thread that was holding and dump your whole bottle of water on your lap. It's not just 1 bad item, I bought 3 of these for myself, wife and kiddo. Person making these needs quality control and to recheck their measurements please.
