Query: Wahl trimmer

I must say I'm disappointed. While the cutting action and accessories are fine, I find that the top metal part / blades tend to rust rather quickly. Looks nice and shiny when you get it, but it doesn't stay that way for long. This item is only a few weeks old and already showing rust. This happened once before on a Wahl I bought a few years ago. I will not buy a Wahl product again, since they both appeared to have this same problem.
