I actually have one dead on mine, and you REALLY have to hunt for it because of the high resolution. Even knowing where it is, when I show someone it takes me a while to find it. As far as I know a 5 pixel policy isn't unreasonable. I've seen some with 8-10 as their policy, some 2 or 3. From what I've heard about Monoprice they don't really fight returns. They will even honor sale prices if you purchased within 30 days. Store credit of course, but that's somewhat typical in my experience with smaller online retailers if they even offer that.
