See what you guys did? All this chat about Aneng made me curious about their gear.
My hobby capex of this month wouldn't allow for an 8008, thus I went for its mini-me version and the cable accessory set. Everything less than US$9.00 with ePacket shipping (with tracking #).
I see no CAT ratings claimed i the ad for that meter. If it has no claim of safety, it looks like a cool little meter for the beginning hobbyist to have for his/her low energy experiments. That is, if can be reliable for such a cheap price.
I have no idea if they are using different chips and if one is better, but I would think it would at least be as reliable as a DT830. Looking at the image, maybe the input jacks are even placed better (directly on the PCB) and may last longer if probes are moved around often. That said, I can't say which of the really low end meters (e.g. sub $6) offer best value. This one is the smallest and offers battery measurement, some offer temperature measurement, some offer a backlight but no battery or temperature measurement, and which is safer... who knows.
Is there something that should/could be added here?

Beginner:
Look at this cool little multimeter I just got from China. Let's see how many volts it is in the wall socket.

Come on, a beginner is just as likely to poke at a wall outlet with that unrated meter as with an AN8008. And just as unlikely to electrocute himself doing it.

I am thoroughly impressed with the Norwegian "beginners", who all know what a CAT rating is.
(And who actively look for a CAT rating, notice its absence, and draw the right conclusions.)

Harbor Freight also gives away these beauties. The convenient on/off switch means the selector can literally be in any position when junior connects the probes.
I am more impressed by Lightages belief in "the power of CAT-markings". As you can see, he finds this meter to be suitable for beginners because it has no fake CAT-rating.
If you now understand that there are two different ESD tests, one with the piezo grill ignitor and one with the new gun, what are you considering the "sparker test"?
Either will do, but I think you should keep doing with the grill igniter simply because it's become a de-facto yardstick. It's difficult to compare new/old results if we switch to something else.
Do those igniters wear out with time? It might be good to measure the sparks and make sure it's holding up, producing sparks just like the first day.There's a fair difference between the two PCBs you show.
They've moved the buzzer and a few components around, yes.
When you really zapped the AN8002 the major trace damage happened around the area of the buzzer. Maybe they moved the buzzer away to improve that area of the PCB.
Regardless, the thing that failed first on that meter was the transistor clamp - nothing to do with PCB spacing or layout. If the transistors in the AN8008 are the same then I'd guess it will fail in the same way.

More putting words in other's mouths, troll.........
You know trolling here, lying about what people say or what their intent is, are reasons for discipline here. Keep it up.....

is everyone that calls you out on anything a 'troll' ?
Tronde delivers the goods backing up what he types,
why is he a troll and you're not ?
It borders on forum slander
What happened? Hopefully no hurt feelings were involved between the parties...
I agree Wilfred. When a person adds to their post, it is a clear declaration of the intent to provoke, or troll.
...I believe that meters should be be rated falsely. That is all I have asserted in this thread.
since when did munching on maccas and sipping cola (example > ) make one a troll candidate ?

I guess anyone, not just Jr, could have the selector literally in any position when we connect the probes to the meter or to the target.
If I pick one of these up and it fails on the new gun, would you send Dave another $20? I need some incentive...
