Crimper costs you about 2$

Pffft flathead screwdriver.

...no seriously if you want to buy a crimper spend 10 bucks upwards or so, people have spent more on screwdrivers. A knipex one costs about 30 bucks, we're not talking fibre splicers here. Regarding outlets, those 10 buck LSA Plus things are perfectly fine. Finagling those things with a flathead is way harder if you want more than an electrical connection but actual signal quality.
