My youngest son has Gator Golf and we've played it often; I wouldn't pay £15.99 for it (but then I'm tightfisted like that) however, for £4.85 I'd definitely say BUY IT and buy it now before Amazon whip the price back up.
I have a real love-hate relationship with golf. My husband plays amazing golf and has a handicap heading into single figures (he's had to relearn to play after breaking his neck three years ago); my golf game is truly shocking - I don't do well at doing things badly, so come September I will be having lessons with a pro' and I won't rest until I can at least hold my own on the green.
That said, I am pretty damn awesome when it comes to Gator Golf putting - all you need to do is putt the ball into the gator's mouth and he'll flick it back to you with his tail; each ball in the mouth is worth one point and you need just four points to win the game.
Aside from the fun element of Gator Golf, it's great for developing hand eye coordination; I think you'll like it and who knows maybe you'll have the next Rory McIlroy on your hands in a few years!
Delivery is free if you choose the SuperSaver delivery option, otherwise there are quicker delivery times but you'll have to pay for those.
Happy putting and then enjoying a drink at the 19th <------ one of the best bits of playing golf!
