Review on 🔧 Volf Golf Shaft Sleeve Adapter: Callaway Mavrik/Rogue GBB Epic Flash/XR Driver & Fairway Hybrid Compatibility - LH/RH 0.335/0.350/0.370 Size by Gordon Turman

Save Money Don't Buy This! While the adapter fits the shaft and head of the GBB Epic Sub Zero screwdriver, the screw threads are different than the actual Callaway adapter. I had to replace the screw in the head of the screwdriver (it comes with an adapter when you buy it) and it's a shame! The point of having multiple screwdriver shafts is that they can be swapped out with a few turns of the tool. I see there is a review that contradicts my review that says the threads are the same as OEM, but I disagree as all the others I have are OEM Epic and Rogue shafts and they are interchangeable without thread size issues.
