+1 for this.  I replaced the leads on my Aneng 8009 in my toolbag with Brymen gold plated leads.  Much more accurate for the low resistance measurements I will be using it for.  I threw the OEM leads out.

Interesting how much noise was in the meter and how much better performance was after Jack made those cap mods.

Looks like he recently fixed up the AN8009 as well. https://www.jackenhack.com/aneng-an8009-improve-accuracy-response/

I've got a lot of responses from people doing the upgrade on the AN8009 and not getting any significantly better results. I did on my unit, but maybe they've improved later batches.

One thing that lets the Anengs down compared to "real" multimeters is the wobbly lead sockets.

strange, i have 2 and they arent wobbly or loose in any way.

The sockets are only attached on the bottom and soldered to the PCB through a long springy connector. It's inevitable that leads that don't neatly fill the gap produce a lot of force on that bottom bit due to them essentially being levers. The supplied leads and maybe the often used Brymen leads seem to fill the gap between the socket and the case and stabilise the whole affair that way, though you can still wiggle the leads from side to side a bit. With the original leads the range of motion is much closer to higher end meters, though.

It should be said that higher end leads also don't seem to be firmly held inside the socket.
