I personally have never gotten a screw extractor kit to actually extract a screw. That is despite trying a dozen times or so on different stuck screws. Instead, I have always had to later resort to making a slot with Dremel and using a flathead screwdriver (the only possible good use for a flathead screwdriver that I can think of).
But I really came to applaud your shortening the amazon link. So many people leave all the extra garbage on links that make them many lines long. That said, you can go even shorter by cutting out the name of the product. Just leave the ASIN (Amazon Standard Identification Number).
