I bought the Cell-Grip Phone Holder to hold my Nokia phone in my car. The holder works great as far as the phone sliding easily in and out of it - but the double sided tape keeps letting go from my car's dashboard. I did follow the directions which stated to rub the area where the holder would be mounted with the enclosed alcohol wipe and wait for it to dry before applying the tape. Either the tape isn't strong enough, or my dash is somehow hindering its ability to stick. Either way, it's kind of disappointing to get in the car and find the phone lying on the floor...
