I am building a school and need this type of clip. I didn't want to spend money on Kreg clips when making pocket holes for various projects I do on the bus. They are quick and easy to set up. They are very durable and don't have much play. I've had them for a few months now and whenever I go to get braces I reach for them. The rubberized grips don't slip and keep my fingers pinched when releasing the tension. I will most likely use the same brand if I need other styles of similar clips. Cheaper than big stores and better quality than HF.
