Not a vine review of free product I paid for mine
I was super excited about this launcher for my little Chihuahua who thinks playing fetch all day everyday rain or shine. Is the reason for our existing lol. I thought I'll upgrade our Dollar store awesome score many yrs ago, he deserves that. (It too came with a ball still a $1.25)
Total complete let down the ball launches straight into the ground or his back. even better the ball just won't release. I have tried the ball that came with,another tennis ball, his rubber ones, no luck
I have had to dramel and shave the inside of the scoop out so ball will release properly. Even then ball can't sit properly just barely grab it. Yes I have tried different throwing techniques move my hand up more quick snap of wrist .
Bottom line I don't want to have to spend my time or his trying to master this ball thrower. I have put in a drawer cause of the nice fold up feature and we will stick with our Dollar store old reliable that would out launch this one any day.
***An update 5/16/26 I was super shocked AllForPaws contacted me with full refund offer. I was not at all expecting that nor was my intention of the review.
5 stars I wld give them their customer service 150% made up for the toy that has unfortunately ended up at Sunnyside Daycare. We will definitely be giving ALL FOR PAWS a second chance, Thank you so much

Foldable Design Works Great and Dog Goes Crazy for It
This ball launcher has become an instant hit in our household. The moment I pick it up, my dog is at the door wagging with excitement, which says everything about how much fun this toy brings to playtime.
The foldable design works smoothly with a simple push button mechanism at the joint. Press the button and flick your wrist to extend it, or unfold it by hand if you prefer. When folding it back, it snaps securely into place. The mechanism feels solid and I expect it to hold up well with regular use. The only way I could see damaging it would be accidentally overextending it when locked open, but with normal handling it seems built to last.
At 25 inches extended, this launcher gives serious throwing distance compared to what I can achieve by hand. The grip is extremely comfortable, genuinely reminiscent of a tennis racket handle with its soft, non-slip texture. Even during longer play sessions, my hand never gets tired or uncomfortable. The ball pickup feature works well too. With the 25-inch length, I do need to bend my knees slightly into a small squat for best results, but it beats bending all the way down and dealing with slobbery tennis balls by hand.
The included 2.5-inch ball is smaller than a standard tennis ball, which actually makes this suitable for a wider range of dogs, including smaller breeds, not just medium and large dogs. I tested it with other 2.5-inch balls I had on hand and they worked just fine in the launcher. The ball stays secure during swinging and walking, so no worries about it falling out unexpectedly. The bright orange and blue colors make the ball easy to spot in grass or other outdoor settings.
The launcher arrives ready to use right out of the box. It's convenient for storage and travel when folded, and the overall construction feels durable enough for regular outdoor use. If you want to increase throwing distance, keep your hands clean, and make fetch more exciting for your dog, this is a solid choice that delivers on its promises.

Thrower is great, ball lasted an hour
The thrower is made of strong plastic. It is nicer than some of the others I have had because it can fold in half to store easier. There is a push button to open it and close it so it doesn’t collapse when using it. The ball cup has a slot in it which I feel helps the ball come out easier. The ball has a soft covering and while my dog didn’t chew the covering off, the ball inside cracked within an hour of her playing with it. Luckily, her other balls fit in the thrower.

Great!
This dog ball thrower is sturdy and easy to use, especially for longer throwing sessions. The length helps keep hands clean, and it launches balls smoothly without much effort. The foldable design makes it easier to store or bring along.
After plenty of use, it’s held up well and hasn’t cracked or loosened. Our German shepherd pups are LOVING the further distance throws! It’s made fetch easier on arms and shoulders, and it works reliably.

My dog is obsessed with this
My dog absolutely loves this ball launcher. The second it comes out he knows it is time to play and gets so excited. It makes throwing the ball much easier and sends it way farther than I can throw on my own, which is perfect for burning off energy at the park.
I really like that I do not have to pick up a slobbery ball with my hands. Scooping it up is quick and easy and keeps my hands clean. The handle is comfortable to hold and does not slip, even during longer play sessions.
The foldable design is a nice bonus and makes it easy to toss in the car or store when we are done. Overall this has been a big hit in our house and has made fetch even more fun for both of us.
