What Is SensorSafe?

The SensorSafe 2.0 chest clip monitors your child’s well-being, sending timely alerts directly to the caregiver’s smartphone if unsafe conditions arise. Originally developed to reduce incidents of children left unattended in vehicles, SensorSafe notifies caregivers if the car is switched off with a child still buckled, if the child unbuckles themselves mid-drive, if the back seat temperature reaches an uncomfortable level, or if a break is needed due to extended seating time. The alert system extends to emergency contacts with GPS coordinates if necessary, ensuring a continuous line of protection.

Not indestructible, but is very tough.
Pattern Name: Ball, Size: Large - 3 Inch / 12 oz
My dog destroyed this, but it took a little longer than it usually does. Would love to know how the lifetime replacement works. There is no information that I see on how to contact the seller.

Would buy again
Pattern Name: Cage Ball, Size: Large - 4 Inch / 8.5 oz
This is a great ball! Both my dogs love it. Queensland is a heavy chewer and I can see no damage. Catahoula loves to fetch and kick after kick and retrieval this ball shows no wear. It’s easy to pick up and is a good size for my dogs.

Very Durable Ball
Pattern Name: Cage Ball, Size: Large - 4 Inch / 8.5 oz
This ball has held up to regular puppy chewing for 3 months now. At first I was worried my retriever would get her mouth stuck in it, but it hasn't been a problem since she has gotten bigger. Supervision required for smaller pups. One thing to note is that the ball was shipped with a strong rubber smell, but that has gone away with use and washing. Super easy to clean! It is a heavier ball making it bounce well and it doesn't damage the walls. Super durable. She's been chewing on it every day and there is no damage to it at all. The scratches, holes, or pieces missing. It's stayed intact for months!

Good ball, but not really for super chewers
Pattern Name: Ball, Size: Large - 3 Inch / 12 oz
This ball is tough...my (foster) dog is tougher. It is a heavy rubber ball, but my Staffordshire bull terrier is able to destroy these balls within about a couple of hours. We never let him chew on these unmonitored. If you have a moderate chewer, this is probably ok for your dog; for any super chewers, you might want to pass. We first bought one of these balls when we learned our foster dog (fresh out of the shelter) had heartworms. We knew we had to keep him occupied somehow, and it is by far his favorite toy (he loves the doughnut-shaped toy as well). We bought MANY of these during his heartworm treatment. Now that he is done with his treatment we won't buy any more of these. They are expensive for what they are. And just be aware that the lifetime warranty only applies to material or manufacturing flaws...not the actual toughness of the product.
