i personally have ventshades on my 5g hatch and they r awesome, yeah it uses 3m but its also tuck under my side mirror so it looks kewl. my friend has it on his ek and it looks sweet.

the weathertechs tuck into the window rubberseals, i have heard stories of everynow and then of it fallin out and it comes all the way down on the sidemirrors, very ugly if u ask me, and its tinted very light makin it look cheap.

the honda access ones is held by clips and metal tabs, study but sucks if u manage to snap one. and did i mention they r expensive. looks the best, fits the best, all oem, but the price tag has some ppl lookin elsewhere.

hope that help u a bit.
