One gotcha. It ships with some cheap chinese AAA batteries which have a slightly shorter body and longer terminals, probably because this makes them $0.0001 cheaper to make since this reduces the size of the battery very slightly. As I usually do, I replaced them immediately with higher-quality batteries (Duracell) and the DMM wouldn't turn on. I finally traced it down to this slight variance in battery dimensions causing one of the batteries not to be able to spring-load up against a contact. A blob of solder on the contact to make it sit slightly more proud solved the problem.

I spent a few minutes filling the back of mine with hot melt glue as well - which makes these things near indestructible and a lot less prone to moisture problems.

Yes, cheap POS, but it's still a lot more accurate than a light on/off tester and as you point out, with the cover closed, tough enough to survive on the bike. And the cheap meter you have when you need it is a lot better than the expensive one left at home.
