You can try and putt with your eyes closed. Hit a few putts at say a 3 foot distance. then close your eyes and try it.. You will feel the putter in your hand and the feed back is great.

I have even gone to the range and hit 8 irons, again the feed back is something you will never get from any pro or magazine or gadget on the market.

This is not for the beginner of golf.

Also get a good insurance before you try it lol...
