ULTRA-PLUS Training collar with Center-Plate & Assembly Chain - Stainless Steel Black

Been using the Ultra-Plus 4.0mm to train our Mastiffs for nearly 4 years now. The 4.0mm says for up to 154lbs, I can attest that they will hold up to the power of 200+lb Mastiffs. After being let down by other collars, the HS Ultra-Plus has been a game changer. Believe in it enough that our newest addition to our pack just got his own. Will never use anything else. Pictured below is the new collar(left) vs a collar that has been used religiously for nearly 4 years(right). Steel links are still springy, plates are showing little to no wear(wallowing out of holes, discoloration, etc), and chain/rings are in flawless working condition. Only difference between the two is the older collar has color fading on the chain and pivot points of the links and plates. Superb bang for buck and quality to last for multiple generations of pups.

I not only love my prong collar for my dog, but I've told others about it and hopefully they'll be ordering it as well.

I have used HS for decades. I will always purchase their products. So glad that I can now easily purchase direct, and not need to use a 3rd party. It's nice to have all the products available, and not just what the buyer at some company decides they will carry.
I have had one bad collar, the ring literally came apart. Collar was not old. It was like the weld was bad. It's laying on my desk, as I still can't believe it happened.
Honestly you really can't go wrong with a HS product.

Title says it all. No problem with the function of the collar, however despite not being a painted product, it is leaving a black coloring on my dog's neck where the collar has sat. Recommend the company revisit the finishing process for this product.

So far so good, it’s been about a week now of slow introductions & use. I ordered extra pieces for potential growth, they don’t appear to be needed atm. The black isn’t causing discoloration to my dogs fawn coat, I’ll update if it ever does. I can’t say there’s an allergic reaction yet, she does scratch sometimes but I’m assuming cause she’s getting used to it. Again, will update over time
