Removal of In-Channel Ventvisors

Has anyone tried to remove the AVS In-Channel Ventvisors before? I ordered a set off E-bay...but got to wondering what if I ever have to remove them due to breakage or whatever reason? That 3M tape is pretty strong...was just wondering how difficult this would be before I put them on.

I have put on several sets of window vents on various vehicles I have owned, including the Ridgeline. The Ridgeline vents (made by Lund) were in-channel and easy to install. I have never tried to remove one so I can't tell you the process. My best advise is to contact the manufacturer. I am sure an email to them will bring a response. BTW, once you get the answer it would be nice if you posted it here.
