Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Perfect for offseason beach days
Winter in New England can be tough for a myriad of reasons, one being the difficulty in ensuring your high energy Labrador retriever is expelling enough energy and not climbing the walls. Luckily, this dreary time of year also means the beaches are open to dogs, and this toy is the perfect tool to make sure your furry friend gets their steps in. It is pretty easy to use and not too large for toting to the beach as it folds in half. The thrower itself is sturdy, although the included ball is a bit flimsy. Backup tennis balls are definitely recommend for public areas anyway. Once you’re done, you can bang or brush the sand right off for easy cleanup as needed. If you have kids, you get double bag for your buck because you can have them take turns throwing the ball or chasing as well. Definitely worth it’s value to tire everyone out and have some fun doing it.

Thrower great, ball not so much
Our german shepherd dog really loves this fetch thrower.
I appreciate the fact that it can be folded when not in use, which makes it a lot more practical to store.
Once you get the hang of it, you can chuck balls REALLY far, and with pretty great accuracy too.
I am deducting one star because I feel like the included tennis ball is just, trash. It's already broken and we've only been playing with this toy for a couple of weeks, and not for very long at a time.
We will be purchasing new tennis balls to continue to play with the launcher though. Overall it's a solid toy and our dog really enjoys playtime with it.

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
