My dog has short fur and the standard contact points were digging into her skin, so these shorter 5/8" ones are a perfect fit. The hypo-allergenic material hasn't caused any irritation since I switched, and they stay secure even during our rowdiest training sessions.

My dog has a thick coat so the longer prongs never made good contact, but these shorter 5/8" points sit much closer to the skin and the correction finally feels consistent. They were easy to swap out and the hypo-allergenic material hasn't caused any irritation on his neck.
