I have not had the chance to use this product yet, but will let you know.

Summary: I've been using a regular shaft for years and recently learned that due to my age I should be using a senior flex shaft. I have ordered a set of woods and irons with senior flex with hopes this will improve my game. The Callaway RAZR Hawk I-MIX I received looks to be the right choice. It's a beautiful driver. All I need is good weather and I will give this beauty a workout. Thanks.
Summary: Great stick!. Callaway never disappoints. bought it from pre-owned but, I couldn't tell. Shrink wrap and all the as new labels. The impact sound is nice. Not the old aluminum bat sound of my FT-iz. Just a solid titanium crack at impact. Haven't noticed any increase in distance----yet, but either a frozen rope or a nice r/l tail.
Summary: I left my headcover on a tee somwhere, never to be seen again. I thought I would have to settle for some generic replacement, but this is OEM Callaway, and Perfect! Shipping was lightning fast and packaged well. Awesome!
Callaway Razr Hawk with a Custome shaft is the way to go

Summary: I have all callaway drivers also but the tour edition of callaway drivers are really awsome. This driver goes long if you put a good custome shaft in it not the stock ones. they are worth less. I put a Fubuki Mitsubishi Rayon Stiff 70 x5ct in mine and that was the difference. The key to any Driver is the shaft that gives you the distance.
Summary: I simply love this driver. I am a beginner to golf and this is only the second driver I have owned. My first driver had a really big head and my drives were all over the place. This head is smaller, the loft degree is smaller, and I am hitting my drives straighter and farther than ever before. I wish I had more insight or experience to give a better review, but as a casual golfer who goes about twice a month, this club is great.
