Caley C owns this product
The Callaway Apex 2021 iron is one of the longest and straightest clubs on the market. In addition to distance, you can expect to get a forgiving iron that launches high and has a great feel. However, if you consider yourself an artist and like working the ball in a variety of shapes and directions, beware that the workability is... Read more
Ideal for
  • Exceptional distance.
  • Predictable results on off-center hits allowing for maximum forgiveness.
  • High launching creating maximum stopping power on the green.
Not ideal for
  • The ball flight will remain consistent. With that in mind, it is difficult to work the ball left to right on command.

I tested the Apex 21s multiples times when buying new irons in 2021. They made it to the final pairing but I went with another set that better suited my game at the time. The Apex 21s has great feedback, feel and solid distance. At first they looked like they had too much of a cavity back at address it... Read more

Vincent P. tested this product
The Callaway Apex 21 irons are fantastic for all players that want to move away from game-improvement clubs but still need some forgiveness. These clubs are cavity-back, forged-style clubs. This results in them feeling smooth to hit but also forgiving. As a result, players that aren't quite ready for blades but also do not need game improvement clubs would benefit... Read more

  • Great Feel
  • Great look at address

Very happy with his help.
5 /5
Took time to listen to my needs and preferences. Provided a lot of detailed information that helped make a choice. Was patient in providing several options, allowing me to make a final decision (no hard sell). He was referred to me and I will do the same to others. Also appreciate the products and options at Curated.

This is something all golfers should look at.....
5 /5
This is something all golfers should look at..... I went overseas and used some rental clubs and smashed them--much better than what I was using at home. I went on line to get some information and Jim popped up as an option on Curate. He led me to the Callaway Rogue ST Max's---I went and tried them locally and they felt better than any other iron I have been trying. I then contacted the club I used for the rental clubs to get them to tell me what clubs I was using over there and low and behold it was the exact same model Jim recommended. The guy is no pressure sales just a font of guidance and genuine interest in having golfers succeed . I can see me buying all my need through him moving forward

5 /5
Caley took my description of what I was looking for and my price point and hooked me up with a great set of clubs at a price that I couldn't come close to anywhere else. Can't wait for my clubs to come in so I can get back to playing the game after a decade away from it.

Grant is the GOAT
5 /5
After my first experience with Grant, I left a 5-star review. I was impressed with how fast he responded, and how well he was able to find me what I needed. After that, I realized I had clicked left-handed instead of right-handed, and my entire order was wrong. I got ahold of Grant, and he submitted a ticket for me and got my whole order switched before it shipped. This dude is the best, thanks Grant!!

Vincent was great!
5 /5
I didn’t plan on buying a driver when I googled ‘best driver’ but within 30 minutes I had checked out with a brand new TaylorMade driver that was customized to my swing and ability. Vincent walked me through everything and made the entire process seamless. He wasn’t pushy at all and seemed to really be invested in getting me the best club to improve my game. I would hands down recommend this service and will be using Vincent’s guidance for future purchases. 10/10

AMAZING Experience with Ryan
5 /5
Ryan nocked it out of the park. He was immediately responsive and provided competitive options to meet my needs. In cross comparing the cost, he was on point. He made sure I was not only comfortable with the on line purchase, but the return policy if they don't play to my liking as well. That peace of mind was the deciding factor in my purchase.

Got me a great deal on a set of clubs
5 /5
I know next to nothing about golf but I am trying to get into the game because I have friends that play. Being a left handed guy trying to get an affordable set of clubs is a struggle. Caley pointed me in the right direction, and found me a quality set of clubs that fit right within my budget. When I sent a pic to my buddy telling him what I bought, he was impressed with the set of clubs and said I made a great pick, however little does he know that Caley did all the real work. Thanks man!!
