The all plastic body is an EV6 I think?
I've always wondered how good those things are..the price is amazing but can they be lasering holes and the other things bosch does to make them consistent at 1/10th the price? But the prize is amazing and they have to be better then old plugged or broken injectors.
There is some really good injector data/info here:

one that is probably most applicable is this one

It talking about modified injectors, but if you just skip through it has some nice tables that show just how good OEM injectors are and that not OEM stuff even the expensive injector dynamics versions are not as consistent. My point being if the cost is no objector folks can't beat OEM bosch, I suspect the low cost Chinese injectors are likely to look a lot more like the lower end modified stuff than the OEM stuff......but that's just a guess knowing the way you normally cut costs is by opening tolerances. There is a reason they say they test every injector and that reason is they need to and they don't define what "matched" is ...1%? 5%, 25%?
Which then being us to this article

Its pretty easy to get a set of injectors to match within say 5% at steady state, full on operation. Its really hard to get then matched in dynamic operation. The cheap injectors and even brand name injectors from 20 years ago I used in the past made fine hp but idled bad....because they were all really different flow down around 1-1.5ms (plus dead time) so 1 plug was white, another black and sooted after 10 or 20 minutes at idle.
Fingers crossed the new cheap Chinese injectors are not 1980 like in any way, I lived through that and wouldn't wish it on anyone
