Aesthetically, the bottle is beautiful; it is thick plastic, so rather solid; she had no taste at first use; it was covered with plastic when he arrived. The plug is screwed; It closes with a "click" (which happens to be the open button); it has a safety that blocks the (a small piece of iron that blocks the release button). There is a small beak for drinking water and it is blocked by a small rubber that prevents leakage. The valve opening is soft and he opens the bottle without touching the nozzle with which we will drink, I think it is hygienic if you have dirty hands. Basically, I advise you. The delivery was fast. The only problem (hence my 4/5) is that the package itself was not closed; we saw the bottle from the outside and there was nothing to really protect it.
