I've had some on mine for over half a year now to test if it helped my wing wobble. I couldn't believe it when a $20 item off of eBay actually worked. 
I get compliments on them, though I didn't mount them as most on here have. I followed the curvature of the top of the rear glass, keeping them equally-short distanced from it (right around the point of the back of roof dropping off) and used the templates guidelines as far as direction. The whole point of them is for them not to be straight. Otherwise they do not work properly to keep overall airflow from departing the surface of the rear window.
They've since been tested on my car in everything from below freezing to 110+ degrees and at high speeds.
