Excellent
Great in every way. Awesome quality. I use the 3/8ths every day so I picked up this to compliment it. Finish is beautiful, knurling is effective, spinning handle is smooth and fast. Highly recommend

Good luck with warranty
Used this very seldom on aircraft and one day the knob came off. Contacted Proto about the warranty and they want me to send it in to see if it’ll be covered. By the time I mail it to them and wait, I might as well just buy another one, but it won’t be this brand. Tekton could teach them how a warranty should work.
