Seem to be well made and solid.
I love how light these clubs are compared to the Big Berthas. I'm getting 10-20 yards more distance with the long irons, and it seems I don't have to swing as hard. Once I figured them out they are accurate also. I'm only 5'7' and 145 lbs and don't have a fast swing speed (mid to low 80 mph)and these clubs help me get the extra distance without having to swing out of my shoes.
The more I use them the more I like them.
I'm glad I made the switch. I was accurate with the Big Berthas but couldn't hit the ball as far as I wanted. It took me a while to give them up but I'm glad I did.
