Can't wait to use em
The product was shipped promptly and arrived a day early. My bench is 2-1/4" thick with 3/4" dog holes. Since I work a day job, I haven't been able to really put them through their paces yet, but I did test them out briefly. Worked exactly advertised. Grips tightly, release when tapped. Appears quite sturdy. I can't wait to put them through their paces. I can't rate them on sturdiness yet, but I'm guessing if my great grandkids do any woodworking, they'll be able to use these. I have it 4 stars only because I haven't used them much yet. May upgrade to 5 in a few weeks.
Rating: 4 stars
