Customer Reviews

F8 Irons Review by Brad
I couldn’t believe the difference with the F8 Irons I have gained 10-20 yds per club and absolutely love the look and feel of these irons. Very happy and excited for many more rounds of golf. (Posted on 3/19/2018)
Great clubs, concerns with grips/information available Review by 11 Handicap
The clubs are great. Gained at least 1.5 to 2 clubs in distance from my ping i5, and I am hitting balls much higher which I needed. Two concerns I have, I ordered the f8+ grip because I like the crossline pattern, however was very disappointed to find out that it is a reduced taper grip (think MCC +4), and this was not listed anywhere on the website. I wish I would have known cause I do not like the larger lower hand, and do not want to spend $80 for connect grips to regrip my set. Also, while I like the idea of the arccos 360, it just drains my phone battery, and I am not a fan of how it adds .25 inches to your clubs, meaning you must use the connect grips if you want to have the length of the clubs consistent over time. If I were to order again, I would probably go without the connect grips, to offer me more flexibility in the future with grip choices.

Overall, I would say the clubs are 5 stars, the problems with arccos and the grip problems described knock me down to 4 stars, almost 3. (Posted on 3/13/2018)
Great Irons, Customer Service and Customization Options Review by Yianni
I'll confess i only just received these irons and haven't played a round with them yet. I did however hit these irons in a fitting i had and swung them great. Longest irons i hit that day and with all the great customization options available, my choice was easy. Also really excited to try to Arccos Grips and at no additional cost, the added value alone is enough to buy these. I had a unique challenge with the delivery of my irons, and the customer service team was really great in accommodating my situation. Really pumped on this brand and am #teamcobra the whole way.

The best Review by Neilanthony
My F8 clubs were delivered early, which was a surprise. They are the smoothest, most amazing clubs that I have swung. Incredible. (Posted on 3/11/2018)
King F8 Review by BM123

The best Review by Neil Anthony
This is my second set of Cobra F8 clubs!
My first set was stolen and I loved these clubs so much, I had to buy the same set again!
These are the best clubs that I have ever played with. The feel, the look and overall performance makes them top notch in my book. (Posted on 3/10/2018)
Cobra King F8 Woods and Irons Review by Bernie
I ordered the King F8 custom made each Woods and Irons. These has got to be the best Golf Clubs I had in my life time! I hit these clubs further then I ever had with the other name brands I purchased. I purchased the senior lite shafts and they performed excellent. I was so impressed with the clubs, that I rounded off my set with a Cobra Tour Golf bag. Also, the Cobra Connect is the greatest technology invented. With your Iphone, you can track your performance with each club. I highly recommend the Cobra King F8 Clubs. (Posted on 3/10/2018)
Great Look Review by Scotty
Great Look, Feel, Distance. Can't beat the price! (Posted on 3/8/2018)
New to cobra Review by Jcwoodwrx
New to cobra clubs and fell in love with the king forged tour irons I bought. Needed some extra clubs to finish out my now 13 of 14 cobra club bag. Awesome clubs (Posted on 3/4/2018)
New Irons Review by Kconley
Just got the new set of Cobra irons. Clubs feel solid and easy to hit. As far as distance is concerned, I am hitting these new clubs 5-7 yards further than my last set. This is only my first round with this set but I feel I will see some improvement with my shot making as I get used to this new set.Great irons, a definite plus in my bag!!! (Posted on 2/25/2018)
Great Iron Set Review by Defchant
I received my F8 Irons about a week ago and they are performing well. I really like the look and overall durability of the clubs. I’m already noticing more distance and consistency with my shots. Quality Product! (Posted on 2/20/2018)
Good irons but .... Review by AndyT
Went for a fitting yesterday - loved the feel and distance. Vast improvement over my (seriously) old current set.
My concern is with the grip choice and the ARCCOS sensors. I like the Golf Pride MCC plus 4 which are not available with the sensors. Do I really value these over my current monitor system? (Posted on 2/6/2018)
Worth the wait!! Review by Christopher
My irons arrived on 1/29/18 ahead of schedule. Cobra offers so many upgrade options at no extra cost is truly amazing. I went with NS Pro Modus3 Tour 120 shafts, thank you Cobra!! (Posted on 1/30/2018)
Love to try Review by Tiger22
I've been a cobra fan ever since I have learned the game. Would love to give these a serious try out. (Posted on 1/23/2018)
