I'm sure this has been suggested before and its possibly on here I saw the post referred to be I'd thoroughly recommend anyone with a Kiox invest £2 in a lanyard to ensure it doesn't fall off. I'd not had a problem but saw a post somewhere suggesting it was a good idea. Bought one off ebay and fitted it. I was out on a ride yesterday and enjoying a long fast technical decent which required a lot of concentration only to find out at the bottom of the run, the display was hanging by the lanyard. That would have been a nightmare to find! The grub screw didn't save it
