Review on 🍶 Nalgene EasySipper: Optimized for Nalgene 32 Oz Wide Mouth Bottle by Dustin Lannan

These inserts I bought fit perfectly in 32 ounce Nalene bottles. You don't fall off the top. They can be easily removed and cleaned individually. However, they do not have a retaining lip and can be pushed too far into the bottle. Therefore, a star was deducted for this error. But they float, so if you push too hard you can easily pull them out with your (clean) fingers. When I push them in they just have to seal with the top and I stop pushing. There hasn't been a single fall or fall yet. Several reviewers complained that they had an odor that required multiple cleanings to dissipate. I cleaned them before use but did not detect any odors. I am very happy with them as they fit well in 32oz bottles, don't fall out, can be left with the screw cap on and are durable. made of plastic.
