For some reason Amazon have put this in the toy section when it really should be classed as sports equipment!.
The Extenda Extension is a quick and easy way to reach those difficult shots at the other end of the Snooker Table without using the cumbersome and wobbly long cue-rest.
Simply slide the Extension onto the butt of your cue, put it on top of the long rest and take your shot. If you had two Extensions you wouldn't need the long rest at all.
A great device to own that helps you to pot balls you'd otherwise struggle with.
