Shock, these are Pintek 4 wire leads that we got a couple of years back. The leads ends to the Kelvin clips were disappointingly stiff and they promised later manufacture units would be improved however we've not got more since then to know for sure they have. Nice leads in every other way although not cheap.  :(

I hope that graphic color LCD will last much longer, I have a lot of meters with them.
LCD are very reliable and easy to replace if the die, but they are fairly limited. Generally I like them, but a DMM can do a lot more with a graphic color LCD (See new Keithley or Keysight).

Some last better than others I guess. My 8840A is still nice and bright, and it and a recently acquired Keithley 2000 are my go-to bench meters.
I love the look of the panaplex on my 7075, and the nixies in my 8300A, but in all honesty I don't use them much (though they work perfectly) and as often as not it'll be a handheld I reach for, just for convenience.

I don't mind if the cables are not so flexible as long as there is a good reason for it. If it lacks strain relief, has molded over clip connections and rotating lantern style banana plugs it's probably signaling a waste of money.

Hopefully they haven't made a connection where the cable splits in two, that would be unforgivable. They have another set of kelvin leads with BNC connectors, seems neither them (unfortunately for me) use shielding.

I own a Siglent SDM3065X.  I do a bit of lab automation with PyVISA.  I use this instrument quite a bit for automated programming and diagnostics.

This is my first bench meter so I don't have reference for comparison with other brands or models.

My only gripe with the meter is that the optional scanner card cannot be added after purchase.  I didn't realize at the time that this is something that would become useful for me to have until a couple of years after owning and using the meter.  I am now considering selling the one I have on the second-hand market and buying a new one with a scanner card.  I would prefer being able to send it in to Saelig (where it was purchased) or Siglent NA and have them retrofit the option.

Sadly not possible.
On one I looked at a few years ago was missing the physical mounting HW and connection looms and componentry for the SC.
