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.
