I purchased the Blackstone iron set 3-PW in early Sept, there was an error with the clubs I received so I contacted them and they immediately acknowledged the error, took responsibility for the error and shipped out another set NIB the next day. So the customer service was great, sometimes things happen and it was taken care of. I’ve played 27 holes with my new Blackstones and I like them, they immediately made a difference. It takes more than 27 holes to readjust and master my new swing (with all irons being identical weight and length) but the concept of a his design quickly made a difference in my consistency and eliminated two ugly shots per round. With some more practice, which gold requires regardless of your clubs, I am confident I will enjoy these clubs for years and drop at least 6-7 strokes off my game within 3 months and probably a couple more as time goes on. And I’ve received many compliments on how striking these clubs look.
