Why assume they don't function or are all broken within a year or two of launch?
Mine's still working fine after 1.5 years.
I did not count them, but something from 3-4 in last 2-3 years. All needed immediate repair/corrction like 40 USD UT61E - not populated input 'protection' MOVs and drifting with temperature and so on. AN870 immediateli aftre populating bettery made them hot , almost exploding them - battery contacts were bended and made short . I found this after a few minues so imaging what could happened if I woud not recognize this. btw. after 'repair' I found that that model has bug - it randomely is switching to mV if switch is on V posiotion. Onother one was stuid mistake of mine - 9V or so attached if switch was on diode position caused 'plush' and it stopped to measure voltage ... Another one simply after a few battery replacements screews were soo loose that the case started to open randomely
Yet another case - rotary switch bacome so loose that useless.
I keep one UT70A alive by plenty of glue in it, it needs regular aligement. I keep it alive because it has 2G resistance range combined with logic proble , inductance mesurement and counter up to 10MHz, but if it will eventually die, I will not cry and not replace it with the same brand.
I do not see any sense to any of the them - 'Save the planet' is becoming valid/important sense here.
p.s.
Yes, I had 'experience' also with Aneng 8008, curiosity was stronger than rational arguments. I gave it to someone after a few days use, as I know that one is simply getting dust.
