X-TireBall Durability
Style: Jingle, Size: Medium
If you have a small dog or a dog that doesn't chew, this is a nice toy to play with.
The labradoodle that received this ball loved it however, since he is a chewer, this product didn't last 10 minutes before it started to fall apart.
The danger is that the dog can swallow the rubber and it will be an expensive trip to the vet.
Summary:
If your dog chews -DO NOT buy this product.
If your dog does not chew - then it's a playful toy.. a cat will like to play with it as the bell is not too loud
I was disappointed that the product said it was for dogs that chew but wasn't

Dog loves!
Style: Jingle, Size: Small
A neighbor found this in town for her dog, who didn't like the ball. She tossed it over the fence for our dog who absolutely loved the ball! The dog ran around the house trying to hide it & bury it, but would go retrieve it after a minute or two and repeat the process! Went to try to find a new one in town, but couldn't, so ordered it. Unfortunately, the ball is made out of hard plastic, which didn't hold up too well to a jack russell's terrior teeth. The ball would be perfect if made out of the "kong" rubber. We ended up using black electrician's tape until the ball totally fell apart...the dog was so sad -- looking all over for her ball, just had to get her another one.

Another winner for my pup; wish batteries lasted a bit longer
Style: Animal Sound, Size: Medium
My dog loves these babble balls, but we always have to stuff them inside another, softer ball so that he can play with them. This tire ball lets him have something he can grab hold of to carry the ball around and tug with us. Yes, these are annoying, but it's a small price to pay when they bring the dogs such joy.
I was concerned, based on other reviews, that the tire would be a hard plastic. It is plastic but it's not hard; it's flexible and "squishes" enough for my dog to grab the toy.
We have several babble balls, and we replace the batteries pretty frequently. That is my only complaint with these; the way my dog plays, we maybe get a week out of the batteries if I let him have it all the time. I take it away from him after about 15 minutes because he gets too excited with it and because he will wear the batteries down so quickly. It takes little L44 button batteries when you need to replace them.
So far he is very happy with this toy, and I'm happy with the price. He loves it.
Update 11/7: both the tire and the ball are dead now. They shredded the tire after about 3 weeks, but the ball was ok. Normally, we just replace the batteries in Babble balls. However, the screws were impossible to get out of this one, and when we got them out by breaking the plastic, all of the electrical parts were rusty from saliva. We replaced the batteries to no avail. I'm a little disappointed because this was a less annoying one than the other two, and there had to be a design flaw because we got long lives out of them (one is still going strong).

HERE'S HOW TO CONTROL THE JUNGLE NOISE FROM IT...
Style: Animal Sound, Size: Medium
This was the first toy my rescue puppy played with at her new home with us five years ago ... it eventually stopped working and was cast aside. I always thought it was really clever and different, mostly because it isn't just a repeat of a couple of noises like some (one especially that is awful, just repeating "hey big doggie, I GOT cha!!" eight million times a day, but has over 20 sounds, per its maker. The other day I looked at the old dead one and got the PetQwerks name off it, searched, and found it on good ol' Amazon.
As several reviewers note--and as its tag admits--"your dog will love it, but it will drive you crazy" --- I didn't think this would he the case for us, as we'd already had one and enjoyed it along with the pup.
BUT I think it is both louder and easier to activate now -- a new and improved version apparently. I think it even irritates the dog, who gives it a "look" when it starts roaring, barking, and screeching across the room, seemingly by itself.
The "key" (pun intended) to this problem is to retain the little clear plastic piece that you pull out when you first get the toy working. This piece keeps the battery from making contact and the toy from giving postal workers heart attacks thinking they're delivering a shipment of fighting weasels or illegal wildlife species.
I had thrown it away. As soon as I realized my mistake, I tried to make a similar plastic piece, with no luck. Fortunately I found the original, and now keep it in a place where it will not get lost. It would be smarter, come to think of it, to put a colorful and visible tag on it so it won't get lost. As it is, it's as easy to overlook as a contact lens dropped on the floor.
Another thing -- I ordered a medium size and got a ball that is larger than I wanted even though my dog is over 90 pounds. It is larger than a tennis ball. Large must be reeally big. Should note also that is is durable and I believe safe.

Lasted less than 5 min
While I get this is not a chew toy, it certainly is designed to encourage playing tug. I have 2 dogs, a lab and a lab/golden mix. They loved this toy and immediately started playing tug on either end of the rope, but when one of them switched to the tire and really dug in with his teeth, in less than 5 min, there were tire pieces all over the floor.
It’s not like they would understand if I told them to only grab the rope and not the tire if they want their new toy to last. I really figured it would be more durable.
