Quality is very good. Alpha makes some very good drivers and they are being used for long drive competition, so you know they're good quality.
Being able to change the shaft at will, is pretty nice. The shaft in a driver is very important, more so than the head in many ways, so being able to change the shaft comes in handy. Very nice looking head design
The head requires a shaft adapter which is 6 sided piece of material. Would be much better if it was 12 sided rather than 6.
If you are looking for a driver but don't know about the shaft, or have two shafts you like, this head will allow you to change out the shaft, or try a new one anytime you want. Callaway has the same thing now. Not cheap, but could be worth it. Can play a low flight shaft on windy days if you want, which could be a real nice benefit.
