The whole is composed of a single block of hard plastic. If there is a problem, we simply buy another one. But for the price, on the one hand, it is not very serious, and in addition, since the time I have, he seems determined not to give up the ghost. I did not expect something that takes over time, and we feel that this is not the product of this most qualitative that is, but so far it never failed me. And I use it very frequently. I could easily put 5 stars if only the product overview page clearly announced that it is not compatible with 3.5 "hard drives (or I have not found how to). Anyway, for HDD 2.5 "and SSD, it's absolutely perfect.
