In my case the cover is not shaky, as was the case with the previous speaker. The closures fulfill their purpose and are easy to operate. In order for the closure of the lid hacks, one need only observe him not only to create, but also easily the upper to the lower part to push together. The case has been meticulously crafted both from outside and from the inside and know no excess glue residues. As only small gripe could name the slight chemical smell I only notice when the case is opened or you can go very close with his nose to the suitcase. But since I do not sit all day in front of this case or cuddle with him, I do not mind that too. If you were to leave him for a while opened, the smell would certainly also soon vanished. For durability, I can not say anything because I have the case only recently.
