Query: I love this bottle!!!

At work they installed water coolers so I wanted a solid refillable container to use here at the office and on the go at other times. I did a lot of research and although this may cost a few bucks more than others, it is really solid. It is very sturdy, and comes in many colors (I chose blue). The only doubt I had before purchase was how the "sipping" mechanism was going to work. I read another review which said that it can be removed without damaging it (or the bottle), and this is correct- I removed it and put it back on as a test. It might seems weird to think about biting and sucking on it to drink your water, and I assumed before I received the bottle that I would just take it off. But I was dead wrong, it is really great to use, and also guaranties that you never spill any liquid. Overall, I highly recommend this product!!!
