I couldn't resist buying another one of these since they were $2.00 today. I purposely bought the "other" meter that has the red switch so we could compare the insides and see which may be better.
Here's the one with the "UL830B" from the teardown above.

And here's the one I bought. I'll call it "K2404":

1. Different pots. Mine had about a 2 to 3 mm piece of bare tinned wire sticking out of the middle leg of the pot. I snapped it off.
2. Mine has the hole on the left for the backlight button. There's another meter that looks like this one that has a backlight button. So I'm guessing mine is the same brand/source as that.
3. I've got a big ground area.
4. I've got a soldered fuse.

5. Under the battery on mine is a + and - in the case showing the battery should be flipped the other way so the wires don't lay across the inputs and I'm assuming wires tucked away on the other side. Sadly they did not install the battery correctly as you can see and caused a potential dangerous situation.
6. My test leads have 1000V melted in to them that looks like it was done with a cattle branding iron with gloopy plastic around it.
7. My capacitor appears physically bigger. It was marked ":N." and "154"
8. It looks like both boards were designed with the input jacks on the side and then were just snapped out and moved to the other side.
Anything else anyone notices to be different aside from board layout?
