Outstanding. I got tired of the official Facebook app simply doing whatever the hell it pleases and draining my battery all day long so I gave this a shot based on a recommendation from a blog. Now  my battery magically has 40-60% remaining at the end of my work day rather than 20-30%. HOW WEIRD. If you are sick of the privacy violations and push notifications of the official app  Tinfoil is highly recommended.
