To-Go Bottle

They seem to work better than the plastic bottles. They keep cold for a long time, but by the same token they take longer to cool down after putting room temperature water in the refrigerator.

I was very optimistic about this product and bought both the small and large versions as soon as I discovered it. However, it does not live up to expectations. First of all, you can only fill the bottle to a very hard-to-see line inside, which is fine for the most part. I added more water afterward, just to get it to the level I wanted for the afternoon. I guess that was too much and it leaked all through my backpack. So that was a drag. The other thing is that it doesn't keep the water as cold as my regular insulated water bottle, so I find that after spending quite a bit on this product, I'm reaching for my old one instead. Finally, it is a bit heavier than most other insulated water bottles which isn't great for hikes, etc. So, kind of disappointing overall.

I noticed after three uses, the rubber stopper from the cap became dislodged. I put it back in place. Also, I'd say it keeps the water effervescent and cool for closer to 8 hours than 24. Looks good though!
