Keeps mostly what it promises

Here was complained on several occasions that the caps do not fit or were flying constantly.
I've lost (0,5Jahre in use) a single piece and of course you have always wanted to see, if you leave the workplace if not somehow times one has slipped out. In the laptop case I lose in principle always one - which is found quickly and reingesteckt again. It served its purpose, and for the price it is unbeatable.
BTW: In principle, they fit all - but some simply do not hold due to the given size so particularly well. The rubber for the card slot, for example, I have nciht even have to plug it in, because it is simply elongated and thus keeps better. So, a certain indulgence was necessary.
