4 Pieces Prong Dog Collar Extra Links Steel Dog Prong Collar Links Pinch Collar Links Correction Collar Links Training Collar Links

These "add-on" prongs are not Herm Sprenger quality and should not be used to extend any prong/pinch collars. Herm's are always rounded smooth edges, I ordered 24 add-on pieces from this company all together and none of them are usable due to the very sharp edges. Would not recommend using this product. Is nothing like the quality of the item they are trying to represent being an "add-on" item for. I will continue to wait for actual herm add-on links so that my clients are not injuring their dogs due to this faulty made product.

Too thick and EXTREMELY hard to squeeze to attach to another piece. These were not made very well. I had to use pliers to try and connect it to another piece, and it took me over 15 minutes to do. I bought same pieces from another place for a little bit more money, same color, same size, but it was made a lot better and perfect for fitting into another piece and easy to squeeze. These are not good ones.

I am working with a rescue GSD and used a prong collar but only ones with rounded and smooth edges - the picture of this product is inaccurate. The edges n the picture look pretty and smooth and when in fact they are flat with rough edges. They will not even fit together without the use of a set of pliers which does not allow for easy application and removal - they are going back and I warn others to not waste your money and definitely dont use them on a dog - terrible product

Badly made; couldn't get them into the collar.

Cheap Chinese links.

Have collar needed extension pieces. Great value instead of having to buy a larger collar

These links were perfect to add to our dogs collar. They fit easily.

I should have read reviews before ordering. Also the dimensions given would have alerted me. Si check before buying.
