Review on Nalgene Easy Sipper: Optimized For 32 Oz Wide Mouth Bottle by Sally Bienz

I love the wide mouth Nalgenes because they're so easy to fill up and add ice to. However, they're difficult for me to drink from when I'm walking or in a moving car. This sipper is very convenient and makes drinking on the move easy. However, it doesn't seem to fit quite right because it's very easy for it to fall into the bottle. The little tab is also not the easiest to grab to remove it. I do like that it is dishwasher safe.I've tried off-brand versions that I liked better.
