These are great!
Size: Medium, Pattern Name: Pack of 2
My dog loves these and now won't play fetch with any other ball. I love that they glow bright so we can play fetch after I get home from work (it gets dark around 5 now). The dog and I both like that they whistle. They also squish easily and he loves to chomp on them while he runs around. Only reason I took off a star is because he chewed a piece of it off and now it doesn't whistle or fly as far. That being said, it seems to stand up well to all the chomping he does on it. I should not have left him alone with it, I think he held it down and pulled on it. If your dog usually makes it his mission to destroy things I wouldn't leave him alone with it, other than that I absolutely recommend these.
Update 12/12/20: I got another dog last year and he also loves these balls. Probably the favorite ball for both dogs, they go into hyperdrive when they see them. New dog tends to be more destructive than the older one and I still don't leave them unattended with these balls, but new dog has not destroyed one. I made the mistake of leaving one in the Chuckit overnight once. Ball was wet from playing in the snow and became lopsided. Now doesn't fly very well but my weird dog still likes it. It is also starting to dry out and crack. None of the other glow balls have done this, I'm assuming it is also from leaving it in the Chuckit overnight.
Other than that, these balls are great. I did read a few reviews that said charging them with UV light made them stay brighter for a longer period, but I did not notice a difference in my quick test of this theory. Just keep a good flashlight with you and brighten them up as needed.

Good for night sessions
Size: Medium, Pattern Name: Pack of 1
Picked this up for evening fetch sessions and it’s been a win. It charges up fast, couple minutes under a lamp or in sunlight and it’s good to go, and the glow is genuinely bright, not the sad dim purple some of these put out. Makes it way easier to find in the yard at dusk, and the dog can actually track it.
It’s a little on the softer side compared to a regular tennis ball, but durable enough to hold up to my big dog, who is not gentle with toys. Still kicking after plenty of chomping and slobber. Fits a standard Chuckit! launcher perfectly, which is the whole point.
Pros:
• Glows brightly and clearly in the dark
• Charges fast from any light source
• Holds up well even with a big, enthusiastic chewer
• Fits standard ball-throwing sticks
• Great for evening or early-morning fetch
Cons:
• A bit softer than a regular tennis ball — a determined power-chewer could probably destroy it eventually
• Glow fades after a while, so you’ll need to recharge it during long sessions
• Only glows if it’s been charged, which is obvious but easy to forget
Tips:
• Charge it under a bright light or in the sun for a few minutes before heading out
• A flashlight works in a pinch if you forgot to charge it
• Keep it out of permanent fetch duty — rotate with a regular ball so it lasts longer
• Not a chew toy, even though it’s tempting to leave it with the dog
Five stars. If you’ve got a dog and a yard, this makes evening fetch actually doable.

Westies Fav
Size: Small, Pattern Name: Pack of 1
Best Westie ball ever, my dog loves this ball. Exactly her size! 3" tennis balls are too big & she rips the fur off. this silicone-ish ball has no fur & is 2&1/2 "
We have 2" balls from her electronic ball laucher, but she still loves this glow in the dark best!

Best dog ball in the world!
Size: Large, Pattern Name: Pack of 1, Size: Large, Pattern Name: Pack of 1
My dog is singularly obsessed with playing ball. He would drop a steak to chase a ball. (He'd return to the steak, but not without the retrieved ball. He's not an idiot.) He makes dangerous leaps, crashes into trees, and runs fast enough to catch thrown balls before they even hit the ground. Since he doesn't care about his own wellbeing, it's my job to protect him as much as I can. And a lot of balls are hard enough to cause him pain or dental damage when he mistimes a catch. Enter the ChuckIt Glow Ball!
The minute Cowboy got his first Glow Ball, he no longer had any interest in the dozens of tennis balls scattered around the house and yard. If I took the Glow Ball away and instead threw a tennis ball, Cowboy would run to retrieve the ball, then return without it and begin looking all over the house for the Glow Ball. The Glow Ball is tough enough to survive Cowboy's big, sharp chompers, yet it's soft enough to do no harm when it hits him in the face. The glow feature is a huge bonus, too. Cowboy gets distracted by chipmunks and squirrels when we're playing, so he sometimes can't remember where he dropped the ball to pursue the interloper. If the ball was exposed to enough light before it was misplaced, it will be easy to find once the sun goes down. (Otherwise, Cowboy always finds it eventually.) When I'm feeling nocturnal, I'll put the ball under a light for a few minutes to activate the electrons, then treat my boy to a middle-of-the-night game of fetch.
I was so happy to see these on sale, I bought a lifetime supply for my pantry. The size guide seems accurate. ChuckIt recommended the large size for a dog of Cowboy's weight and that size is perfect. Highly recommended product.

This is a big ball.
Larger than I thought but still a great toy for a heavy chew pup, easy to toss and won't go under funiture. She has the same ball in a 5 inch size so I know it's quality and will last. Can't wait for Summer, will make a great yard ball.
