great product. Saves time because you don't have to screw them or ratchet them. You just squeeze the notch with special pliers and you are done. Buying them in bulk will save a little money. Always make sure you press the notch till both side touch or you could end up with a disaster. I have one engine go out on me at 9 miles out at sea. I was praying it was something minor. It turned out to be a hose had popped off because I did not crimp it right. These things apply just the right amount of pressure on hoses and do not damage them by over tightening.
