Terrible design. With most dog ball launchers, swinging your arm like you're throwing a baseball results in a long arching trajectory of the ball, just as expected. The same arm motion with this launcher results in the ball flying straight up. To get the ball to even move forward requires an un-natural forward snap of the wrist, and even then it doesn't travel far. Hasn't anyone tried this out before hitting the market?

Great product

Style: dog ball launcher

Very easy to use, assemble and disassemble. Saves my arm a lot. Unfortunately once my dog runs to the ball she gets side tracked and I have to fetch it. 🫤 I highly recommend this product.

Mid at best

Style: dog ball launcher

It’s mid at best. Requires a little trick to get it to go forward and not just fly up in the air., it’s also not telescoping. It just comes apart into two pieces.
