I got some of these and they are as advertised L-O-N-G off the tee. However when you get close to the greens, and need the ball to check, they don't provide enough backspin.
I've found them to be a durable ball, stands up to play well, but the only real issue is the spin. These are advertised as a distance ball, so for what they say it does, it does it well and I give it 4 stars, it's just not my cup of tea.
It is VERY hard, and I prefer a softer ball, so that is the only reason I ding it 1 star. I can only assume that the design process that gives it more distance is responsible for the hard feeling. It is HARD. Not as bad as a range ball, but still, I felt it was quite hard when I hit them.
Still, they are as advertised, extra distance.
