The bottles are super. Beautifully large and practical. Only the wide opening interferes a little bit, but that you can see in advance and reading (Widemouth) to the images yes I therefore do not understand some reviews, where it is referred to as negative. I bought an extra cover for these items and can normally drink. BPA was free very important to me, as a person annually introduces by drinking water from a plastic bottle in wrong about his body. So always use BPA free!
