I bought one of these Phoenix reverse bleeding kits a few months back.

Worked decent on my tow truck. Good pedal feel afterward.
I like the idea of pushing fresh fluid from the bleeder up to the master cyl.
Trapped air rises easier than trying to force it downstream.
I plan on doing hydraulic clutch work soon so that was another reason I bought it
