The firmware will get refined.
If you have an issue then report it in the thread for this:

I don't understand the big surprise about the slow autorange.
(*) It appears to do better than 0.5% in tests but you'd have no right to complain if it didn't.
(*) It appears to do better than 0.5% in tests but you'd have no right to complain if it didn't.Did you mean 0.05% ?
Anyway, I personally want to keep the conversation technical. And for me the biggest questions are: 1) can community help somehow with the issues
Apart form reporting issues, no they cannot. UEi are in control of the firmware.
I have the actual firmware but we have not even tried to compile it.
FYI the U1282A which uses the same chipset auto ranges from OL to short in 2.5 to 3 seconds(still rather slow) so a speed increase with new firmware may be possible.
Me either, but I am getting a certain amount of shadenfreude from the wails of anguish in these threads.
A whole load of people seem to have bought this meter without watching any of the videos Dave/joe has been posting or reading any of the threads on what it is or where it comes from. I guess that's the EEVBLOG effect in action.
Reality check: It's mostly an off-the-shelf, 0.05% meter*. It's not a meter designed by Dave, it's not been built to his specifications.
It's a good meter for the money. It's safe, it has data logging, it has Bluetooth, it has a bunch of features that not many other meters in this class have, eg. display of power. These extra features are the reason you'd buy this meter, IMHO.
It doesn't have any of the fancy laser-trimmed resistors, etc., that make Flukes what they are. If it was a Fluke 87 for half the money but with loads more features then we'd have known about this brand a long time ago.

I think it's quite reasonable to expect a meter with the EEVBLOG branding on it to meet certain minimum standards, like acceptable autorange speed.

I think it's quite reasonable to expect a meter with the EEVBLOG branding on it to meet certain minimum standards, like acceptable autorange speed.This is the reason for unbiased reviews. The meter has a lot of features and minimum standards will mean something different depending who you ask. Even if Dave felt uncomfortable with producing a review because of the bias (perceived or otherwise), I was hoping he would send a few off to the large YT channels to review before offering them. I thought the guy that offered that high speed camera had the right idea. Sure there were sites that it was wasted on but a few sites really took the time to show it off. I think that paid off.
I think we are just starting to scratch the surface on the UEI meter. Give it a few months. I did go back and look at my Gossen BTW doing a side by side comparison and I would say the settling time is a wash between the two. The Gossen is ever so slightly faster (half second or so).
Risks and challenges
Like all hardware projects, hardware is hard, and "sh!t happens".
Do we know the actual update rate on the bargraph? the manual only states “fast updating" and then there is the “5 times per second nominal”.

should I take your statement as a confirmation that the 121GW is indeed slow?
I wouldn't know.

The Gossen is ever so slightly faster (half second or so).The point I was making is that you'd expect that Dave, would tell the manufacturer that it needs to meet certain minimum standards.
It has features that make it unique, but if it's inadequate in other areas, it lessens its value as a general-purpose meter that improves upon the competition and becomes more of a niche instrument that only gets used when the unique features are needed
Do we know the actual update rate on the bargraph? the manual only states “fast updating" and then there is the “5 times per second nominal”.Could we get a figure or estimate on the bargraph update speed? (or is this info also >hidden< in some now deleted videos or comments thread)

I agree with you and assume that the time required the the meter to settle was considered to meet their minimum standards. However, that does not mean it meets your minimum standards.

I read the manual and you appear correct. I had made a video showing the speed of the prototype compared with my BM869s and UT181A. These are some of the fastest ones I have come across. I can tell you that the prototype was not as fast but still impressive. I could make that clip public but would rather someone run the released version instead as the results may be different.
