Most people that play predator I've talked to weren't sure how it would fit so haven't bought one.. The wife got me one for christmas. its pretty simple to install. You take the old bumper out of your cue and replace it with the one it comes with that has the screw hole in it. they give you an allen wrench with it to tighten it but I would have to say thats unnecessary...I got it tight enough by hand. The extension itself goes on tight in less then two turns which is good. I want it go together quickly when I need it. I'm sure it fits differently on different predators. I have a road line and as you see it's not a completely clean fit. you can see the space on the edges but it is tight and doesn't effect how it works. Just doesn't look clean esthetically. There about $90 bucks on Amazon which seems a little high.. but it's a gift so she really didn't care lol I will say it feels better then the omega billiards one I was using before. it doesn't add all the weight on the back of your cue like that does.
