Hacking Question RCMLoader Switch Dongle?

[OneForAll]

I saw some really cheap Switch dongles named 'RCMLoader' on Aliexpress.
I haven't seen anyone talk about this one.

Here are the names of some of the listings of it, as I am not allowed to post links.

HeroAngel 2018 RCM Loader for NS Switch dongle SX OS Shorter Injector JIG kits
HeroAngel Loader for Switch dongle SX OS RCM NS Injector JIG kits shorter Connect
1PCS 2PCS 5PCS RCM Loader for NS Switch dongle SX OS RCM NS Shorter + Injector JIG kits

And yes, there are more listings as well.


Is this any good?
