Review on 🐶 4-Link Steel Prong Dog Collar - Extra P by David Chen

We bought these extra links for the original Herm Sprenger 2.55mm collar to make it wider (dutch shepherd in training) but they are definitely thicker than the collar links. We also bought real links (triple price) in black and they matched perfectly. Therefore I would not recommend these links if you need them for a black Herm Sprenger 2.5mm collar. Just choose an authentic brand. That does not work. They are thicker than stated and very difficult to put on a collar. And they don't have the same bending quality (jamming) that affects the functionality of the collar.
