On a recent shopping trip, I noticed that the Wilmington Costco store had a fresh supply of both Kirkland putters and the wedge set. My first impressions of these Kirkland wedges was, they have a nice finish, grips are ok, grooves are even and well done. They have True Temper shafts. I did experience some vibrations on ball strikes that I have never felt using Vokey, Cleveland, nor Calloway wedges.
