I wonder if any of the sellers will take a screenshot of the thumbs up in front of the meter and add it to their for sale listing .
As usual, why the 1000V CAT II / 600V CAT III nonsense? It could almost have been a half-decent meter for beginners or as second meter for low level signals if clearly marked CAT I 50 V and ranges limited to 50 V, and might even meet those safety requirements. The main downside would have been the missing current ranges.

Extend the current ranges and swap the hold button for a rel button and.. it's almost perfect. For $25.
Maybe not your intention but I just bought one based on your review. $21 delivered and shipped from a US seller.
Wow! It's such a decent little meter with 10000 counts...I wish it had the µA range though . But overall, its really good for its price.

If you're worried you can scratch off a I and get a more realistic rating.

Dave measured 1000V in the video, it seemed to hold up.

Dave measured 1000V in the video, it seemed to hold up.Handling 1000 V AC does not come close to satisfying the requirements for 1000 V CAT I. 1000 V CAT I requires safely handling a 4000 V transient from a 30 Ohm source (12 Ohm source for 600 V CAT II).
I think you would also need to scratch away two zeroes in addition to the two I's.
Does anyone expect those tiny fuses to handle that without arcing? The non-existent input protection? Minimal clearance?
In other news: The sibling AN8002 survived longer than a Fluke 87V in joe's electrical robustness testing. There's no reason to think this will be different, the PCBs are almost identical.

Q) Are the meters that fail your tests unsafe? They all fail in a safe manner and although non-functional it presented no safety risk in that failed condition.
A) I have no idea if any of the meters I have looked at would fail in a safe manner or not if tested to the IEC standards. If you want to know if a meter is safe or not, have it tested by an accredited lab or buy one that has been certified by a third party.
I loosely based my testing on the IEC standards. The tests I perform are at much lower energy levels than the meters what these standards call out. This is why we never see the explosions like you would when watching some of Fluke's internal testing. I don't expect the general hobbyist is going to know about CAT ratings or the IEC standards.
