Rated 5 out of 5 by from As expected from Callaway..A great club I've had every Callaway iron produced in the last century it seems & every new set I get they are better & better. These OS irons are definitely the best Callaway irons thus far. Might try the new Rogue irons but its hard to believe they could be better then these OS. I've said that before but Callaway manages to beat my expectations with every new model. By the way...this holds true with Callaways Drivers, woods & Hybrids. Best club manufacturer in the market. They blow away Taylor Made who waste all their time in marketing advertisements vs. producing a better product. By the way I'm a 71 yr. old 4 handicap & know a thing or two about golf

Rated 5 out of 5 by from I also left a Ping G to try these out, and they are most certainly longer than the G's were. I bought these and they are the finest irons I have ever hit. I hit several shots that raised the goose pimples. The thing that really surprised me is the chipping ability, they are excellent chippers. I hit a lot of shots at the flag. I need more time to really appreciate these. Yes, they are expensive, but no different than TaylorMade/ Pings/Titleist. I got tired of buying clubs that didn't work, and bit the bullet and got these. I have shoulder issues and need some help, these deliver.

Rated 5 out of 5 by from Outstanding irons!! I previously had the X2 Hot irons with stiff shafts, but decided to take advantage of the "trade in/trade up" offer, and move to the Big Bertha OS. Personally, I love the looks of these irons, especially the 4 and 5 iron which some say look "hybrid-ish" but to me, they just look like easy to hit long irons. I moved to regular flex shafts, and I don't know what others are doing, and saying these irons are a club shorter (maybe their previous set were really strong lofted?), but I find these irons to be as long and maybe even a bit longer than my X2 Hots were, but my accuracy has increased GREATLY! I love the feel of these irons. Some say they feel dead to them, but I still get the same feedback as my previous set. I can feel when I hit it a bit thin, I know when I hit it towards the heel or toe. I can really tell when I flush it! My normal shot is either pretty straight, or with a baby fade. I have found I can work these irons right or left like my previous set, which I thought would be very hard to do with a maximum game improvement iron. I love the finish of the club head, and although I haven't played but about 4 rounds with them, I have hit them for many hours with my SkyTrak, and I like how the face looks like they have barely hit a few balls. Overall, if you've like past versions of Big Bertha irons, you are going to LOVE these!!

Rated 5 out of 5 by from Changed My Game I always thought I needed to use my woods to get down the fairway consistently. I was wrong. These clubs are the perfect fit for me. I do not hit the ball perfect every time but at least with these clubs whether I do or don't, the ball stays on line and pretty much goes where I was aiming. When I hit it right the distance is nice too but the accuracy is incredible.

Rated 5 out of 5 by from OMG! i just purchased the Callaway Big Bertha irons 3 weeks ago and like any new/ different irons, you need to distance them. And due to the wind conditions in Florida I'm still not completely dialed in. But I've I played 3 rounds with these clubs and they are amazing! LONG AND STRAIGHT. We played Sunday afternoon and I found myself on the 18th 172 yards out with 160 over water with a club to a club and a half of wind in my face and didn't think twice about going at the pin. Golf is fun again.

Rated 2 out of 5 by from Length Is Inconsistent I traded in my Ping G irons hoping to gain more height with a stronger pop but neither was achieved. The length of these irons are nearly a club shorter than my Ping G irons and the feel off the face of these irons feels almost dead...

Rated 5 out of 5 by from Long, forgiving, and great looking These are the longest irons I have ever played! They are also very forgiving. I have cut 4 strokes off my handicap since I got them!

Rated 5 out of 5 by from My scores 10 strokes better that last year. That's the main or only point to it. The best irons on the market.I hit every iron farther than any irons I have had in the pass. Very easy to hit with these irons.
