Thinking of fitting a screen extender prior to my trip to France 
my mate in France has fitted one from Ali express ? Any opinions/comments welcome
I have one from ebay, £7.99, been on for 18 months and 12000 miles, it works and is a bargain !!!
i have 2, one was 15 quid from ebay fitted on a MG travel screen, looks ugly but does the job, and a puig one i got from the MGCGB marketplace which i have fitted to the stock short screen ready for when the weather warms up.
i much prefer the puig design but haven’t had a ride with it on yet. i expect it to be at least as good as the ebay item if not better.
travel screen was causing bad buffeting over 60mph and the ugly but effective ebay item has cured that
