have bought this model at the hardware store to me years ago. on the one hand has become from the connecting web of the main buckle so that it no longer close properly. on the other hand are the main lid and hinges the cover for the small fan at the top of the same. which are only quite loosely attached, so when you open the big mouth can sometimes even the small peel with. and since then on his head, come to meet one then all small parts. and then it also includes no longer correct. So that made me nervous much tasted the construction.
