Review on 🐶 Herm Sprenger Ultra-Plus Prong Dog Training Collar - 3.0mm x 16", Steel Chrome Plated Prong Collar for Effective Dog Training, Pinch Collar, Correction Collar, Dog Supplies by Amanda Smith

I'll update the rating. I bought this collar with an easily detachable pin literally 2 years ago. I gave 5 stars at the time because it is a well built product. But two years later, the spring in the clasp didn't hold up. There's nothing quite like rescuing your dog from a broken feather. I tried using a regular spiked collar for a couple of weeks but it was a poor quality product that kept breaking. I've looked everywhere for a quality spiked collar like this but found it difficult. Decided to take a risk and buy a second one. I was going to rate the product below 4 stars due to the clasp failure but after seeing what's on the market this really is an excellent product. This time I decided to buy a guarantee. I'll see what happens in two years.
