Review: Worked well for the job I had - Use to get the hollow nut off my old type 1 vw oil filler - bit into and grabbed the inside of the nut really well. Much easier to use than trying to get into the slot in the top of the nut.
Review: Worked perfectly for me - Was trying to separate the oil filer from the alternator stand on a VW T1 engine using the recommended socket attachment with no joy! Someone recommended this so at the cost thought nothing to lose. Worked perfectly so no issues recommending it.
