Any experience of adjustable clubs

I am considering buying the adjustable club fron Q-CLUB. Does anyone have experience of using this club please? Even better does anyone in Gloucestershire UK have one that I could try out at a driving range?
Recent wet weather has closed many courses, or limited them to carry only. That’s become too much hard work for me, a single adjustable club sounds attractive. I know that are not PGA or R&A approved, and this reason is given by local golf shops for refusing to sell them. Adjustable clubs are fine for social golf - I never play in tournaments.
Hoping someone can help with experience or a trial (worth a pint and a meal in the clubhousr).
