I got these at the last minute while we were shopping for other golf items for my sons birthday. I came across these QOLF Balls Limited Flight Golf balls, which I thought would be great for his limited room practice we have in the middle of the city here. The balls are about half the weight of a normal golf ball and the dimples are triangular in appearance. It says on the packaging that they are also used with a specific game " QOLF the off-course golf game", when I went to their site I found the game but have never seen it locally here. It looks fun but it's kind of expensive for basically a target to swing at. I think we will just keep using them for the practice qualities and continue using a coffee can for our pitching wedge practice. I really like the QOLF practice balls they tend to limit the distance by about half that of a normal ball plus their really bright colors easy to spot for old half blind guys like me.
