I went ahead and bought the precision screw extractors to remove the two pentalobe screws from the bottom of my phone. They've stripped pretty badly.
The problem is, I have no idea how to use them. I can't find anything related to this kind of extractor on the web. I think you are meant to hit a hammer on the top of it, but it doesnt seem to do anything.

Use a screw extractor like a normal screwdriver to remove the screw. Be sure to go slowly, and press down hard enough to prevent slippage and engage the burrowing threads.
If the screw extractor can't get a grip, you may need to drill a small hole into the screw head. You will need a drill bit that is designed for drilling metal; a wood-drilling bit won't survive. Be careful! If you drill too far, you will destroy the head entirely or make it fragile enough that it will snap off, making it even harder to get the screw out.
Also try using a small piece of steelwool or a piece of the green abrasive on kitchen cleaning sponges- press a small piece into screw head, insert screwdriver and turn.
The abrasive material will bite into the screwhead, and give better grip for the screwdriver.
As a last resort if the screw is too badly damaged for the screw extractor to work properly you may have to drill out the hole using a bit size the same as the shaft of the screw. Remember to work incredibly slowly, use a tool to hold the piece in place and you can never be too paranoid when working with such small screws to make sure you're not going too far.
Good luck!

Which direction do you turn the extractor?

These are actually supposed to be used by gripping the outer edge of the screw head. See this video: https://www.youtube.com/watch?v=kfcU2f7S...

With all due respect, the precision screw extractors with x-shape tip is a joke. I can't see how it could work, with or without abrasive from sponges. Actual working extrators have a sharp reverse-screw pattern that cuts into metal when rotated counter clockwise.

I think it works like a regular screwdriver, but it creates its own place to screw in, without actually drilling into the screw. This makes sense for smaller screws due to a slight mess up can destroy the threading.
Thanks Dylan, had the same question and thus did the trick. Stew out & kids toy 🧸 working again.

Certainly NOT hit with hammer unless of course you want to totatly destroy the phone - that is your choice.
