Hi all. I'm experiencing a second incidence of this issue. Firstly the backplate of my 9 iron came away and was lost during a round. Now the 7 iron backplate is off. Scottsdale Golf in the UK was the supplier.
The clubs have not been exposed to any extremes of temperature and only used on a couple of rounds before trouble.
Waited several weeks for the replacement 9 iron. Let's see what happens either the 7. Never had a similar issue with AP1 and AP2 clubs I've used in the past.
