Consumer Reviews
The most comprehensive body of golf equipment reviews can be found at GolfReview.com. This website provides a database of consumer reviews that covers the full range of golf club manufacturers and club types. When you start looking at a particular club or a new set of irons, scan GolfReview.com to see how golfers, who have already bought and used the club, like it or dislike it. When reading the the club reviews, it's best to focus on reviews from golfers that seem to play like you. Generally, golfers of similar playing abilities will usually have similar experiences and opinions regarding clubs. Since all major brand golf clubs are well engineered, the real trick to finding the club(s) that are well matched to your game. Note that most reviewers provide their average golf score and often the shaft stiffness and ball carry distance, so it is usually pretty easy to identify golfers that have similar swings and skill levels as yours. Here are some direct equipment links for the GolfReview.com website.
Note that the GolfReview.com reviews are primarily useful for clubs that have been in production for a while, since it takes some time for meaningful reviews to accumulate. Therefore, when new golf equipment first comes out, the best sources of club reviews are the major golf magazine publications. Generally, these reviews are conducted with a small group of testers that represent a normal range of golfing abilities. But since these reviews are usually limited to small, selected group of items, you may not always find the reviews that you are looking for. Since the number of testers is relatively small, the review information may not be a comprehensive as GolfReview.com, but it is the best review source for new golf equipment. Links to some of the most recent reviews are provided below.
