Doesn't wrinkle and keeps its shape, and Golf balls fall and stay into the holes well!

Only other criticism is that the foam is fairly forgiving so the holes are generous

With the proper 'holing-speed', 7 out of 10 putts drop when they hit any part of the hole and that's the highest obtainable percentage according to Dave Pelz

Should have stayed away from the fancy 3 hole thing in the first place.

The holes are the right size and I love the little upslope.

The ball catcher in the back is nice, and having multiple holes to aim at is nice as well
