My wife and I both got one of these a few weeks ago to replace the plastic bottled water we are used to drinking from. We use it on the commute to and from work and at our desks at work. They are great. The water tastes as good or better (from our filtered fridge) than the bottled water did. My biggest beef is the bottle is a bit larger than a water bottle, and so although it still fits in my backpack, car cupholder, etc., it is tad bit more cumbersome in my hand. The previous reviewer noted that these bottles "chirp" like a bird, and they do. However, I found that if the air hole is straight "up" (closest to your nose) when you drink, and the water inside is not up against the hole, there is no chirping noise. It takes a bit of concentration/practice, but during a meeting last week I used the bottle several times in the space of an hour without any chirping. All in all, this is a well-made, great stainless steel bottle that we plan on using for many years to come. Finally, 26 oz is NOT a liter according to Google, who state that "1 liter = 33.8140226 US fluid ounces." But these bottles are still plenty big enough for our uses.

I purchased this bottle 5 months ago. In that time it had fairly regular use and sustained a fair number of small dents, which seems to be fairly common with this type of bottle.

However- I was VERY much taken aback the last time I filled it and it had developed a pin size hole on the side of it- not where any dent was near. This causes a water to run down the side of the bottle and renders it useless.

I think 5 months is much too short a life for a stainless steel bottle. I wish I had invested the money in something that would last. I contacted the company and was told that returns were handled by the seller, no guarantee by them.
