Herm Sprenger 3-3.25mm Black Stainless Steel Spike/Pinch/Prong Extra Link - Package of 3: Enhanced Dog Training Tool Review

Works well. Like the Herm collar I bought. Each link adds about an inch to the chain's length. Expensive but the only option I found.

Exactly as described. Have only used it 3 times but it works well to stop stretching. I just wish it could be connected more easily. It's not hard but I have arthritis in my fingers so sometimes it takes some time to heal.

I first ordered a Herm Sprenger collar for my Cane Corso through an authorized dealer. I needed more links as it grew but shipping to HI from the original site was expensive. I ordered them and they fit perfectly and are holding up very well!

Either they sent me the wrong size or ordered the wrong size by mistake; Anyway, I bought two packs of these ridiculously oversized links that require 2.25mm links. Shouldn't be a problem, but they WILL NOT RETURN. Be careful!

This is a fantastic training collar. Good quality, nice looks and the added bonus that it's a lot easier to put on and take off than other brands; It's almost like the metal has more flex than I would give. This is especially good for those who have joint/arthritis issues and don't always have the dexterity to use other brands.

Too bad I didn't wait to buy when I ordered a collar with spikes for my dogs. I had to remove two links from the collar I ordered which together with these three extra links leaves a total of five links. I don't normally leave negative reviews but as of writing this review they cost less than $5 but when I bought them last week they were $13. Not to mention I can't return them for anything, not even a stinky Amazon credit.

I have ordered extra links for the Herm Sprenger Pinch collar. My dog was a bit underweight when I bought the collar (it was a lifesaver). When it came back I had to add two links. The links are easy to add which says a lot because I have multiple sclerosis and my hands and fingers don't work very well. If I can add them to my state, anyone can add them! The extra links are just as good as the original collar. The black paint will not crack or deteriorate when added. Very well done.
