I appreciated its help with developing my golf fitness and swing speeds. Unfortunately, due to restrictions imposed by an ongoing physical ailment, I could no longer continue with the recommended rigorous routines [I am in my early 70s]. The driver attachment is transferable to other club manufacturers with the right adapter, which can be purchased.
I would certainly recommend this to anyone seriously considering improving their golf conditioning.
Andrew and his team are meticulous with the advice and instructions provided.

I've been able to add about 3 mph to my swing speed after only about 2 1/2 months of training. By using a simulator I've also been able to see what launch angle and rate of backspin maximize distance for the same club head speed. I hope to add a few more mph before spring! Speed Stix is a good program that requires a commitment to the training - you can't just buy another 10 yards - you have to earn it!

My swing sped has gone up appreciably and I’m now adding 10 to 15 yards to my drive. I’m 60 years old. This has been a godsend

It’s a great product because I get to use my own shaft.

An easy way to improve your speed (Length) with not to much hazzle. Easy to attach and super exercises as well.
