SAVE YOUR MONEY, THESE ARE UTTER GARBAGE UNLESS YOUR DOG HAS NO TEETH (MAYBE)!!
Size: Large, Product Packaging: Standard Packaging, Size: Large, Product Packaging: Standard Packaging
For all those purchasers who are posting videos of these toys while talking about how great they are and how long they have lasted at your house, would you mind disclosing the breed and age of your dog(s) that play with them? I only ask because I am finding these "positive" reviews REALLY hard to believe now that I have firsthand knowledge that, as a chew toy, this thing completely sucks. Based upon personal experience and the physical and photographic evidence, your dog might be an OBSESSIVE chewer, but they are most assuredly NOT a "power" chewer. If they were, you would almost certainly be posting reviews saying that this toy is utter crap, just like I'm having to do now.
After many years of experience using Kong brand toys, the idea that this toy is the "most durable" Kong toy is just ridiculous, and blatant false advertising in my opinion. It took three of my dogs (a 5 year-old Boxer/Pit Bull mix (2nd pic) I'm fostering and two one year old border collie puppies) all of five minutes to completely shred FOUR of these toys straight out of the delivery box. I was the proud owner of four of these things for all of five frickin' minutes out of the box. Meanwhile, it previously took the Boxer/Pit almost two years to destroy two medium-sized Kong "snowman" shaped toys, and even then he wasn't able to shred them anywhere near to this degree. And believe me, he actually *IS* a true "power" chewer, as after raising and training dogs for over 50 years, I have never seen a dog completely break that type of Kong chew toy.
As an aside, Kong (the company) appears to take crappy product claims only by means of printed hard copy sent via the U.S mail, so no immediate relief for your wasted expenditure on their products will soon be forthcoming. How many modern companies do you know of that don't allow some sort of online contact for product claims, even if it's just an email address? So I might very well have to reconsider whose products I am willing to spend my all-too hard earned money on.
That said, those three dogs are all now outside throwing up chunks of these crappy toys that they swallowed while tearing them to pieces, and which I now find myself hoping really are non-toxic!! The regular "snowman" shaped Kong toys are MUCH more durable than these things are. Had I known that beforehand, I would have spent my money accordingly. The picture I posted is the last remaining toy out of the four I ordered, and I most certainly want my money back (wish me luck)!! This toy is a complete WASTE of your money for any dog that is bigger than an aged chihuahua or that actually has teeth, so I suggest that you DO NOT purchase.

The same magic as the extreme chewer Kong cone!
Size: Large, Product Packaging: Standard Packaging
My lab hound mix LOVES this tire as much as he loves his extreme chewer Kong cones (we bought three of those!). He hasn't been able to cause any damage at all in the week or so that he's had it. We are always excited to find toys that he can't break! We're ordering a second tire for upstairs!

Great training tool
I bought this for my working line GSD for training. It’s awesome. The rope isn’t too long to handle during training sessions but still long enough I don’t lose a finger when paying out. The Kong holds up well, as expected. The only concern I would have for anyone would be the integrity of the rope on a heavy chewed which is the reason for the 4/5 star review. If used as a freely available toy left unattended with a moderate to heavy chewer the rope wouldn’t last very long. But I do love it!
