I was skeptical at first, because I already had such a bottle in another embodiment, and from other manufacturers. There was drinking rather cumbersome. Everything works great. The water tastes very good. If several occasions bought later by friends. Perfect for traveling. Does not matter. Perfect size. Has very high. 2 thing I have to complain about, however .: 1. The cover smells lyre still to plastic so I always drink upside down, so I do not have to smell it 2. Unfortunately, the famiy does not quite to the bottom, so you can not drink the last of.
