I heard that netflix was great if you like the sort of films that they sell in buckets at petrol stations

It normally comes with 2 screw both different lengths. Good luck if you email them, I tried a while ago regarding something else and never got a reply

I emailed them at least a week ago about a problem with my helmet mount. I’ve since sorted it myself but still haven’t had a response from them

That may be a good shout, the only problem is the bit that connects has a metal surround, hopefully if I’ve done it right you can see it in this pic, so not sure how effective it will be, unless the surround comes off maybe
