I recently bought one of thse drivers, and WOW! What a difference! I'm hitting longer and straighter that I ever have. I've added 30 to 50 yards to my drives, and I use the draw shape driver which has just enough face closure to help straighten out an errant shot. I've cut 5 to 10 strokes from my game already, and I've only played a few rounds with it so far. All of my golf buddies have tried it, and about half are thinking of getting one of their own. It's a real confidence builder, and I expect to improve my game greatly because of this driver.
I don’t think it comes up to the same quality standards as the original liquid cement, or the tube type that I grew up with. This is more like a glue than cement, and acts as such, by simply gluing the parts together instead of melding/fusing together like traditional plastic cement.
Glue connections are not as durable, and in some cases break away easily.
