I still have not pulled the trigger on a Gossen to run. These are the three I am considering for my 2000 follower review. Functionally none of them are as good a fit for me as the Brymen BM869s or the UNI-T UT181A.
M205A $243, 6000 count, basic meter
If I go this route, it’s like buying the low end HIOKI just to see how they do.

It can’t measure conductance, can’t measure two temperature inputs, has no bar graph but they offer a BT version.

Measures conductance and it can measure power. Dave did a review of it and it looked like shit on the inside. Some tacked down axial resistor. I was not impressed. I asked Gossen if this was a production meter as they link Dave's video. No response but Howardlong provided the information below.
I am leaning towards the Ultra being a better fit and something I would actually use. If you own one of the Ultra, I would be very interested in hearing how you like it. Any problems?
Gossen provides a link to your video and I asked them if the meter was a proto or if the tacked down resistor was current production. I have not heard back. Did you ever find out?
I guess it is no more and they had a re-spin, this is mine, purchased about 18 months ago.

Thanks for the picture. Looks good. After 18 months, any complaints with it? The only bad comment I have seen was on Dave's video where the person shorted the current inputs to the mains and damaged the meter.
I hardly ever use it. Being an Energy meter with simultaneous I and V, I bought it on the premise I'd be able to use it for measuring microcontroller power in and out of low power modes, but I'm afraid I've found it's useless for that. The relatively slow auto-ranging means the burden voltage changes so it has too much effect on the DUT. I really should've thought that through!
I am sure it's good for higher power simultaneous I and V.
The other thing is that there is a physical prevention of you having probes plugged in and/or moving the dial in certain modes with probes plugged in. I find it a bit of an irritation, a bit nanny state if you like, I'd rather it beeped at me instead.
The ground probe is stackable at the meter end which means it protrudes out. Now while a stackable probe is great in some circumstances, it means it won't fit into its purpose made case with it plugged in. I like to have a meter ready to go, probes connected, you can't do that with this meter if you use the carrying case.
I find using the meter itself a bit daunting, the UI isn't too obvious to me, I find I have to refer to the manual. This may also be down to lack of use though!
Despite being soft power on, the two AA cells are the same ones supplied with the meter 18+ months ago, so that works OK.
I would say that it does look the part when you get it out on the bench!
With apoogies, this is off topic.
