Anything thing worth noting, most often send spare adhesive pads for this exact reason. So check the box if you still have it
That's a really good point. You've prompted me to go rifle through the box in the garage.
Think i'm so conditioned to just about everything being 'extra' these days, I hadn't thought to check.
But a big shout out to the guys in Halfords who gave me one for free. I walked in and said I was going to make their day with my annoying ask and they laughed, got one out of a box and gave it to me in goodwill. I was happy to pay for it but they insisted - they deserve a bit of recognition for being decent.
