The
UNI-T UT-210e will be useless for measuring low currents typical in many electronic circuits. Its resolution on its lowest DC range (2A) is +/-1mA and accuracy 2.5%+ 3 counts. You could of course improve on that by using a large 10 turns coil through the clamp, but that only gets down to 0.1mA and doesn't help the accuracy any.
For general electronics work you really need to be able to measure below 10mA with better than 5% accuracy and at least three digits resolution. OTOH, pair it with an EEVblog
µCurrent and it will be adequate generally and, due to the µCurrent and reasonable accuracy on DCV pretty good for low currents.
In its favor, its got detachable leads so you can make up custom ones for specific applications. However, its a little bit chunky for a 'pocket size' form factor. Maybe if you habitually wear garments with cargo pockets it will work for you.
The form factor is likely to be an issue impeding your search - most slimline pocket multimeters don't do current.
