I was researching how to change the spark plugs on my subaru and everyone said take it to the dealership due to the difficulty. After watching enough video, I decided to do it myself, but one reviewer recommended this tool to fish out the plugs once they are lose. The job would not have been possible without this. Being able to contort the magnet and have it remain in that position saved me so much time. Most magnets are either straight or flexible, but with no memory.This is a game changer for trying to recover nuts, bolts, washers that fall into the abyss. I cannot recommend it enough.
