I've not used that brand that I know of, but brake master cylinders
are something I've had very bad luck with if I buy from the FLAPS.  I
have returned as many as three bad ones in a row before getting a good
one.

They're also easy to mess up if you use the "pump the pedal" bleed
method -- if your helper pumps the pedal all the way to the floor you
can damage the seals and then it won't work.  If I have to use that
method I put a block of wood under the pedal so it can't go all the
way down.
