This is probably the first and last time I make a comment on a trash can, but there I am obliged. This is quite perfect in its style. The opening mechanism is fully responsive. It was probably my main question when I bought it, but you approach just above, it opens immediately. Then closes quickly enough when you walk away. This could turn into a gag so is simply a fluid gesture. As for the noise mentioned in other reviews, I just do not understand. Sure enough, she did a little squeak at the opening and closing, but what is the problem? I will not put too forward the ecological side, as rechargeable batteries are still less than green no battery at all, but it condones. In the human-objects War, this trash is perfectly servile, submissive, faithful ally.
