So far so good. The monitor works with regular golf balls and foam balls too. So using it indoors was a snap. You get 1000 credits so no problem there. Getting the ball centered for tracking takes some time but once you figure it out it's easy. HINT:The ball needs to be offset from the Square almost a foot or more to hit the launch zone. Also be sure to wait to hear "ready" before you swing. Compared to a $4K or $5K simulator it's well work the price. My wife and I enjoy setting it up in our living room and playing a round whe we can't get to the course. I'm telling all my friends to get it too.
