I carry several of these for my IT work. The other day, during a torrential downpour here in Oklahoma, one of these dropped from my Waterfield Sleeve case and full into a puddle in my driveway. I didn't notice it til I got home that night. I shook the thing out, threw it in my oven on 165 degrees, and left it in there for about 5 hours. I was taking care of my 3 year old son and forgot all about it until I was locking up for bed. Took the darn thing out, smelled a little cooked, lol. Today, I brought the adapter into work with me, plugged it in, and it worked without a problem. I will keep an eye on it over several weeks, but I am pretty darn impressed for a 15 buck ethernet adapter.
