I've put about 1,000 miles on it and while it's been a solid performer I would say it is prone to punctures. I've had several with very small metal wire that I would have assumed would not penetrate the rubber.
I have over 3500 miles of paved road riding, without a flat tire, and on the rear wheel. The tire surface is getting a little flat now, so plan to change the tire within the next 500 miles
