The smell, you can also say stench that emanates from the products already very disturbing. Bought in April, he had eased up this morning not felt. As I came up with the idea to put the item in the blazing sun. After about 3 hours the stinking Impregnierungsmittel was nachezu evaporated. At the next opportunity I will also treat the inside so. Then everything will be fine. The closure is indeed made very solid, but to open it firstly requires both hands and then a bit of flair. I've seen the same closure in some other brands. One can definitely say that never opens by itself. I bought this product because all 7 subjects have the same size, also lockable. The safety chain I removed because I do not need them. Some reviewers have criticized the small holes at the 'federal'. These are obvious fabrication conditions, since they were also present in most other brands.
