This is the best interchangable system available. The weight is good and the reliabliality is excellent.
Ordered 5 All-Fit adapters and multiple collars. The first attempt was to be used in a Tour Edge C723 driver. On the second swing the driver head flew off because the adapter screw wasn’t long enough.
2nd attempt used a longer Cobra screw with the Tour Edge head. After less than one round of golf the adapter was loose and was easily removed. Despite prepping the adapter based on warnings from previous reviews the adapter still failed. The ferrule remained glued to the shaft and the epoxy was confirmed to have cured properly prior to using the shaft. It was not a bad epoxy job or the result of incomplete mixing.
My initial enthusiasm for having a Universal adapter is cooling off. I will try again, but my confidence has been diminished severely.
Product works really well. Can easily swithc between heads. Just be careful on the rubber gasket, if yoy change too often, the gasket will wear off and then you will have a loose fitted head
Excellent quality. ,missing instructions only
