Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Boredom Buster
Color: Green
This ball has been a boredom buster lifesaver. On the first day my 15 week golden retriever puppy played with it for a good 2 hours straight. I was nervous he would immediately get bored with it but nope, he searches for it every day. It has helped with his puppy teething, he's more likely to play with this ball than come up and use my hand/arm/clothes to teethe on. The battery lasts a good amount of time and is quick to charge but I did wish it lasted a bit longer. Overall I'm very happy. We live in a top floor apartment but the noise doesn't seem to be too bad for the neighbors. It's good quality and seems durable.
Edit: The velcro for the sleeve wears out within a couple uses. It keeps falling off. It was my puppies FAV thing about the toy because of the pull tag thing. So now it's ineffective for him. Not sure if there's a way to get a new sleeve or not.

One of the best dog toys I’ve bought off Amazon in a long time
Color: Green
My dog Rosie is a heavy tower so it is difficult to find balls she doesn’t destroy quickly. I came across this item on Amazon and it is honestly one of the best pet toys I’ve ever bought on Amazon. After a long day of work sometimes I come home and Rosie has a lot of energy. I turn this ball on fast mode and she has so much fun. I do worry about how much shaking in her mouth. I don’t wanna give her a headache, lol but there’s also a slow mode that you can press for the ball to slowly move around, but it’s a really good toy and I’m happy. I purchased it if you have a heavy tower, I wouldn’t worry about them breaking it because we’ve had it for a couple weeks now and she’s doing great.

Not indestructible, but dogs love it
Color: Green
My dog LOVES this toy. Unfortunately, she loves it so much she destroys it. I have now purchased FOUR of these, but if left unattended for 5 minutes, my American terrier breaks this apart. She loves it so much though, I keep buying replacements. This is a wonderful enrichment toy, but you must keep an eye on your toothy friend.
