Older Macbook Pro.... great machine, failing hard drive. I removed all but 3 screws from the case... those last 3 all were stripped, and nothing I, not the guys at the local hardware store... could do to remove them. I don't own a dremel, and did not feel like spending that kind of money to get one, without even the certainty of success...
This extractor kit was priced right, and sure enough, I was able to remove all 3 screws using the various sized tools that came with the kit.
Go for it!
