I have also encountered the same problems on installs. We use a strong Glue or the red double sided tape you can buy at home deput. Double sided indoor/outdoor tape works great. I'll be glad when blinder comes out with a smaller head or new design. Leon over at Blinder is a great person and is always there to help. Its good to get advice from forum members, especially if your new to the whole jammer industry. Hats off to Blinder once again for great customer service!
