For short range chipping, this is awesome. I've actually chipped in several times over the last month and left ball super close to whole a lot of times. Definitely worth it if you do a lot of short range chipping.

I know a few people who have this wedge, have seen the improvement with their sand play / chipping. And for the amount it costs I thought why not. I have to say I'm surprised at how easy it is to get out of the sand.
Easily put it works

Good

Bought this club in hopes it would help with getting out of bunkers more consistently. After learning to trust the club as it is designed, my sand save percentage has more than doubled and I occasionally use it for flop shots around the green. It may look a little odd but it definitely does what it is advertised as once you get used to using it.

*3 Month update*
I wanted to update my original review after 3 months of use with this club.
My original findings are still accurate, however there are a few things to note.

* The club saves me an average of 2-3 shots per round. My index has dropped to reflect this.
* Tight lie pitches (10-25 yards) are easier now with rarely any chunks. Very pleased.
* Bunker use is still good, however it is hard to control precise distance with this club. This can result in leaving an 8-10' putt. The upside is I don't think even one shot was left in the bunker using it these last 3 months.
* Hitting out of thin lies in bunkers (i.e. unknown barely any sand) is still brutal. This club doesn't help much there. Shots still go sailing long or over the green.
* The swing weight of the club is quite heavy. There is a lot of metal in the head. Distance control has been good everywhere else besides bunkers though.
* If you are a super good bunker player, then you wouldn't be looking at this club in the first place. I just don't want to spend that much time practicing them anymore.

Initial Review:
(For reference-my current USGA index is 10.7)
Our bunkers in this area have inconsistent sand. Some is hard packed, some almost muddy, while others are soft and some have the dreaded 1/4" skiff of sand under the ball. For me, these conditions are too hard to adjust to and they cost me a lot of strokes due to inconsistent bunker play/conditions. Also, we have a lot of tight lies within 50 yards of the greens. Currently in my bag are wedges by Cleveland, Titleist Vokey, and Callaway. Now there is this C3i replacing the 60^ Vokey. Two playing partners have purchased this C3i wedge prior to me doing so. I have given them enough ridicule about this club to fill a small bunker. Well, low and behold I finally tried one of theirs out. It was a 65^. I threw a few balls in a bunker and tried a few different lies. Much to my chagrin, it was too easy to hit the shots out. My stomach started to ache from all the crow I was eating. Executing short to long shots just meant swing a little longer arc. The darn balls just popped out of the bunkers, as long as you set up square and hit about 1" behind the ball.
I then tried hitting shots from tight fairway lies. Again, 90% of the shots were easier than a standard wedge with 10^ bounce. Also, these grooves were making range balls actually bite more than my new Cleveland RTX4 wedge.
I bought the C3i 59^ wedge as I found my buddies 65^ to be too much loft. I had to hit flop shots with too much force to make the ball flop at over 15 yards. I find that the 59^ worked just fine on initial testing for flopping short sided practice shots.
I will give this wedge more time in the bag and see how it plays out. The biggest drawback I have found so far is that the leading edge (see pic) of the club has already lost its paint after hitting 30-40 practice shots the first day. Not good. I will try to update this review at a later date.
Hope this helps!
