It's easy to see how they got the price down - drastically reduced complexity (at the cost of drastically reduced features).
Only 4V, 30V and 30ma, 300mA ranges and no input protection to speak of (it says "50V max" right on the front panel). No ACV (or ACI), no Ohms.
Also the input impedance is uncommonly low with 3.22Meg, at 6 1/2 digits this can create an significant error even if the source has an impedance in the single digit kiloohms.
It makes sense for industrial automation, but an optional high impedance input would be cool for a lab bench device.
So they don't need: input protection, 1000V capable input divider with all it's ranges, divider compensation for AC, TRMS converter, switcheable current source for ohms, high impedance buffer for the divider; and all the mux-ing, amplifying, controlling and initial engineering (and verification) that would come with all that.
I would also assume they don't pre age them, so expect to calibrate after a year or two to get it back to accurate after all the stuff has gone through it's initial aging (and hope it settles there...).
If this capability is all you need for the job (they seem to have industrial automation in mind) or your mixed signal home workbench, why not? I could see a place in the latter case, if you have a scope and a more rugged (but less precise) full-featured handheld already, this would allow to enter the DC precision realm very cheaply. They question is, does it hold true to the specifications.
With all that said, I'd love a look under the hood
