Bests & Worsts Reviews from Amazon

Followed instructions to the "T". Used on low speed. Created the hole and then flipped the bit over and inserted the extractor. First screw came out with a little difficulty but it worked. Same done for second but the bit broke. Examining the break shows the metal to be brittle as it did not break at the "neck" or other thin area. It split from the extractor head vertically down the shaft. For the price I wouldn't recommend the product. Other similar extractors sell for much less and perform the same. Would be a great product if a better metal were used for the bits.
