Product has 0 utility for hanging anything vertically. Anything held vertically WILL fall. However, it will allow you to securely stick ANYTHING to your car's dashboard including: cell phone, radar detector, GPS, sunglasses, etc. I bought a magnetic mount for my cell phone with a suction cup attachment that wouldn't stick to the dash. I used a square of the Gripeez which is slightly bigger than the suction cup and attached the suction cup. It grips like iron. For holding things horizontally, product is amazing.
Bottom Line: Yes, I would recommend this to a friend
