40,000 Count Multimeter under $50 - HoldPeak HP-770D

This multimeter appears to have been out now for over 4 years now with essentially no attention on the EEVblog for hobbies. Per the linked video, it seems incredibly accurate for the cost (measuring down to 1uv) but lacks the safety features of a Fluke.

Anyone on the forum have one? I was thinking of buying a few more Aneng 8009's (~$25) but for double the cost, I get 4x the counts (9999 count vs 40,000 count) and additional features. Opinions for hobby use?

If 'hobby' means you're never going to exceed measurements of about 50 V then it is good enough. Above that it is not safe. This is valid for all cheap DMM's. I've got to use an Aneng AN9002 sometimes and, while it is actually very nice for the price, I will not approach it to anything like mains voltage because if I make just one wrong move it's potentially the last one I'll ever make.

Sounds likes this will be your first DMM. Don't give the specs and features too much importance. What you really need is a stable meter giving repeatable measurements. Repeatability is much more important than absolute accuracy or precision. Example: if you measure a value you want it to be in the ballpark of what you expect, that is close enough, you likely only need it to be within 2% or so. Any meter can do that. What you do care is that next time you measure the same value it effectively shows up as the same value so it gives you trust in what you measure and can be compared to another measurement.

Off course it is nice to have 0.1% accuracy, but you don't need that. Same for anything less than 10 mV, you don't care. And when you start caring about these things you need a much more elaborate lab.

GigaJoe:
have one of this

"Incredibly accurate"  probably quite exaggerated

it has microvolts, but shorted it shows -7 microvolts now. usually it off from 2-3 LSN to 5-7 depending what you measure. limit 42000 useful to work with batteries where around 4V. (vs aneng 9999 )

To turn on backlit you need to stick an electrical tape on the top center , where the sensor is located.
speed is average \ mediocre - especially basic resistance algorithm switching down step by step ....

So overall it is an average thingi .

My daily usage is overclocked owon b41t+  (with 8M crystal instead 4m)  - it measures any resistance 0.4 sec delay - very fast , useful if you need to find one in a haystack.  it 22000 but precise to  1 LSD ;   it a bit off more as i add more tvs diodes, thermistors , varistors. GTD.

Can't be assed to watch the video.
Does it actually measure voltages like 1μV or -3μV or does it round everything less than ±5μV to zero in order to hide its offset voltage?

This meter has been reviewed at lygte-info.dk and I remember finding something about it that made me prefer the Aneng AN870 as a cheap, high-ish resolution handheld.
