When I first got my hands on the water bottle I did notice a couple of things: It is definitely a bit weightier than your usual plastic or aluminum water bottle, and the BPA-free coating can feel a little strange (it adds a "thick" sort of feeling). But after using the water bottle for just a couple of days I quickly became used to the weight and feel.
I take my pure bottle with me everywhere. It fits nicely in my car's cup holder without falling over and is the perfect water bottle for desk-job folks or students. It is easily portable. The only thing I wouldn't suggest is going for a run with it since it is a bit heavier than other sports bottles.
I got a lot of inquiries and compliments on the water bottle from my colleagues at work. Do you know why? Because it's sexy as hell. The water bottle really does have an awesome look to it. It's beautiful, sleek, and streamlined while still being functional.
The only real qualm I had with the water bottle's design was the screw off top to the opening for drinking. I'm a grown woman, but I do tend to lose small things easily. This is the reason I always steered clear of Legos as a child and earrings as an adult. It's just not a good idea. So when I saw that the blue screw-off top wasn't connected to any other part of the water bottle to prevent it from being separated from the bottle, it made me nervous. It's really only a matter of time before I take off the top and it's lost to the bowels of my car forever. That will be a sad day.
All in all, it's a great and surprisingly durable glass water bottle. Seriously, the video on the website shows a woman going at this thing with a wrench for a pretty long time. The water bottle will last. If and when it does break you don't have to worry about its contents adding to a landfill for eternity and beyond.
