⭐⭐⭐⭐⭐ Awesome. Did exactly what I needed to remove broken exhaust manifold studs.

Works great. Soaked one broken and one stripped turbo exhaust stud in PB Blaster on a turbo still in the card for a couple days while I waited for this thing to arrive. Easy to use, and once it did I had the broken studs off in about a minute with little effort. The tool is like a drill chuck, but with six teeth that bite into whatever is left of the stud and the more you turn to loosen the more it tightens to grab the stud. Awesome, a great device.
