Simple! Easy! All We Needed!!
Size: Large Triple
These were the only durable rubber like rings that were both the same material; not too thick (not heavy) so my 1 year old Pit, Dixie, was able to latch on to one ring while we grabbed the third ring, leaving enough space so she won't accidentally bite us when grabbing the rings to play. They were also the only ones that came interlocked and cannot be taken apart. She is also a big chewer, which means she can gnaw on these without tearing them apart. The rubber is thick enough to play, but thin enough to twist and flex with her. So far, they are sturdy. She was immediately so excited! Simple and easy!

Great durable dog toy!!
Size: Large Triple
We have a medium-sized dog (45 lb mixed Aussie/Hound) who is a pretty aggressive chewer. He also loves playing tug-of-war with his canine and human siblings using these rings. This is easily his favorite toy. We bought one a little over a year ago that he plays with daily. If finally broke this December just in time to buy a replacement for Christmas!
The prior one finally broke when the middle ring came apart at one of the thinner rubber points. He still plays with the intact outer rings as well as his new toy.
I wanted to dock this 1/2 star for a few reasons: 1) it is not completely invincible, although I would argue a toy that lasts over a year with pretty constant play for an $11 price tag is a great value. 2) the one we received is not yellow/black. It is blue/green. I was personally thrilled it was blue/green because it ended up being an exact replacement of the one we had previously. However the description does not say "colors vary" and it was hard for me to tell when ordering if I was ordering the correct replacement toy. A clearer description would be appreciated. 3) This is a great toy for one dog, but our other dobbie/cattle dog mix has no interest in them. So not all dogs will love this toy (obviously).
4.5 stars isn't an option so I'm giving this 5 stars because it's just about as close to a perfect dog toy as one can buy (at least for our dog).

Great toy, as long as dog is NOT ALLOWED to chew on it
Size: Large Triple
Let me start by saying that I like this dog toy. My big dog LOVES tugging with it. As long as you keep away when the dog is in a chewing mood, it lasts a long time (my 1st one lasted a year), however, it WILL NOT last if the dog chews on it, as I found out with this one. A friends dog chewed on it while she was behind a snow mound (mostly out of our sight) when it was only a week old. One end ring was barely holding together when we discovered her chewing it. Fortunately it was an end ring, so I still have 2 connected rings for tugging with.
It is a great tug toy! But it is also a TERRIBLE chew toy, so make sure to take it away when your dog starts to chew on it and it will give you long service.

Fabulous toy!!
Size: Large Triple
My GSD is always up for a good game of tug-o-war. I purchased these in large and I think I love them as much as my dog. They are super strong and hold up to his 100lb self pulling on one end and my “blah blah-lb” self pulling on the other. (Ha! You thought I would say how much I weigh) I even bought another pair for our cabin so we have some to play with at both places. He isn't a sit and chew on things kind of dog. He gets plenty of playtime and bully sticks for chewing. Not to mention that I wouldn't let him use them as a chew toy anyway. There are toys for play and toys for chew. Therefore, I cant say anything on how they hold up for chewers. So if you let your dog just sit and chew on it instead of giving them something designed for strong chewers, then no it might not hold up to that. All I can say is my German Shepherd is 100lbs with sharp teeth and stronger than me now and honestly he is probably stronger than I have ever been in my life, and they hold up to the pulling and tugging of both of us. Thats what they're designed for and they serve their purpose excellently.

Won't purchase this one again.
Size: Large Triple
J.W. used to make a ring toy such as this, that was softer & thicker with a smaller black ring in the middle, that our dogs all, absolutely loved!!!!! But this one totally bores them to the point none of the dogs will pay it any attention! Please bring back the original 3 ring toy, that J.W. has now changed to just the one ring! I feel like they must have discontinued the toy with the 3 rings they used to sell, with the smaller black ring in the middle? I won't waist my $ on another one of these! Sadly, none of our 3 dogs will play with this specific toy at all! & I generally prefer to purchase J.W. brand toys for our dogs. But this toy doesn't attract them in anyway. It just sits around.
