Protex branded parts any good?

[notNA]

First of I would like to admit i was a moron in this instance.

Recently i ran into an issue with my car with the brake master cylinder leaking

I started off by calling ford to find out pricing and got quoted $1200 to $1600 then proceeded get annoyed at the ridiculous price they quoted.

Spoke to my mechanic who hasn't done me wrong yet he recommended a aftermarket protex branded master cylinder which he has been using and hasn't had issues with and mind you he works on stupid powerful cars like 9 second XR8's etc

The mechanic also tried to get a genuine master cylinder and was getting shafted as well, he showed me the prices and had the phone on speaker as he was speaking to the guy... i know his mark up his honest like that and doesn't dick you around.

by the end of it i was thought stuff it and went ahead with the it and bought the protex branded one at less then half the price installed with my break system fully serviced and bled.

Had a look at the unit and looks identical to the PBR one that comes on the car and works the same and feels the same to me.

Basically just want to know if its good or if i should start saving and try and swap it for a genuine one when i can?

TL : DR version basically want to know if its a crap brand or if its fine

Sorry for the long post with all the punctuation errors, typed this up on my phone while.
