Lure clips, good lure clips like the Instinct pro Quick Clip do not effect the lure's actions. Lures swim as if a loop knot had been tied. The clips generally weigh less than the towing split rings that are sold with many lures.

 Quick Clips come in a variety of sizes. Some lures like cup-faced poppers with a small tow point may need an additional split ring to work with Quick Clips.

They are a great option for most anglers who don't want to waste time tying knots or replacing leaders after multiple lure changes. With practice, a lure change is done in mere seconds. At the end of the day it will mean more fish caught as you can now quickly fish all levels of the water column before moving on.
