Works well. Satisfied with the controllability of the clamping pressure. All of my other Jorgenson clamps use threads for tightening and have spoiled me. The purchase price was higher than I had planned, but there were four in the pack, which made it a fair price (rather lower in value) in my opinion. Processing, high-quality materials. I expect they will last longer than my economical versions. Some of my Jorgenson clamps have been in service for 30 years and are getting more and more reliable. As the durability and handling of this product is pretty good I think I'd rate it as pretty good value for money. I intend to buy more.
