Love this ball launcher! Just buy it!
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
These throwers are THE BOMB ! I've been using them for 4 years. The squeaker on it is a big hit at the dog park and with my dog. Gets dogs attention. Buy the squeaky chuckit balls to go with it. Easy to clean, holds up really well.

Squeaker Pinches Hand
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
I toss balls 50-75 feet into the air. Works our my dog. I can actually throw a ball over 150 feet, so the dog gets a good workout. The squeaker is unnecessary and it does pinch my hand on a long toss.
