Really love this toy. Let's us throw the ball much farther than we could otherwise. Dog loves the glow ball, holding up great. The glow even works pretty well, and you can use this Medium size with regular tennis balls too.
My Lab would play for hours, this saves my arm. We don't play for hours, but she would like to!!!!
This is all the fun of a regular chuck it... but it doesn't matter what time of day you play! If you lose the ball at night... no worries. It glows! AND SO DO THE THROWER!
