Heko wind deflectors.

They are very good, Jase, but seek oot the wans that FRICTION LOCK, as opposed to these which are more than likely relying on double sided ticky tape to secure.
The ticky tape isnae that ticky, sometimes allowing for slight movement of the deflector and allows the glass to contact the residue left behind by the tape. This spreads all over the bliddy glass whilst upping and downing the windae, and requires copious amounts of Tardis to remove from the glass AND the rubber draught seal the deflector sits inside. All of the forewenting was via personal experience on both Funnerburd Wan and Funnerburd Too, which was a shame because they looked the bog's dollox.

Meant fur tae say.......it was only the DRIVER's side that came adrift, due to much more use of lekky windae operation, Jase, but Tankers is right......best on marquet are them Heko wans......investigate them doing clip or friction lockers though. I used extra ticky tape at time of fitting too, and although the Heko edges are reduced thickness to fit the channels, they still mildly snagged the closed location of the windaes.
