Query: Just bad.

So many cons, I'll start with pro.Pro:Looks pretty good on the car.Cons:Requires that you cut it down because it's not machined to proper size.Does not prevent rain from getting in while driving with windows down about 1/3 of the way.My driver door window guard fell off after 2 days because the adhesive sucks on these.If you have a manual window crank, prepare to overstress it trying to share the window gap with this thing. Takes too much force to close window.If you have automatic windows, prepare for your windows never to get all the way up again and potential burnt out window motors.Creates air leaks that you will hear on the highway.2/10 would not bang.
