Query: Flimsy and fragile

I bought this to work with my Macintosh. I needed a wireless USB adapter to work with my wireless keyboard and mouse. Since this was the least expensive unit, I bought it. I installed it with no trouble, and it performed well. After owning it for a couple weeks, I was moving my computer around and bumped the adapter against my desk. The two halves of the outer plastic casing popped off and the metal connector bent slightly. I popped the case back together and straighted it out, but it no longer worked. Since I thought it was my fault, I bought another one. I had only owned the second one a couple days, when I bumped the adapter with my foot while crossing my legs. Guess what? The same thing happened. This time I don't think it's my fault. The price is good and the performance is okay, but the construction is flimsy.
