4.0 มม. สแตนเลสสีดำ Herm Sprenger Fur Saver

My previous fur saver was a cheap knockoff and the links kept pinching. These 4.0mm black stainless links slide so smoothly and the prongs are rounded enough that corrections feel firm but not harsh. Worth every penny for a strong puller.

The 4.0mm links feel solid without being too heavy, and the fur saver design really does spare the coat compared to a standard choke. My only gripe is the black finish scuffs a bit after a few weeks of outdoor use, but the training results have been worth it.
