Great usability
I prefer this version over the non-foldable stick, as this one I can fit into my bag and carry it out easily. Great size and has a locking feature to prevent it from folding up when throwing. Highly recommend, my dogs love fetch and it is hard to chew if they get their hands on it.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.

Great to keep your dog entertained
Color: Blue
Great toy my 13 month old cane corso absolutely loved it and it kept her entertained forever except she has an extremely strong bite so she was figuring out a way to split it apart so I had to take it away -it’s extremely strong, but not strong enough for the bite of a cane corso but any other dog would love it. I just wish my dog didn’t have such a strong bite and would be able to keep enjoying it since it is a little expensive the only problem with it is that I thought the remote shuts it off, but then her bites were making it come back on, so I don’t know if it was my dog or the toy just doesn’t stay off until you turn it on.
