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.

Wouldn’t buy again
Style: dog ball launcher
Compared to the namebrand thrower this one sucks. It just throws the ball way up in the air.
