Thanks to special clamps with a rolling system, inserting the phone into the holder is easy. When using for the first time, adjust the size of the clamps according to the width of your phone and then easily place the phone between the rollers with one hand. The rollers safely secure the inserted phone and hold it firmly even in the event of the most severe shocks caused by driving. For safe use of the phone while driving, use the swivel joint to set the phone to the ideal angle so that it is clearly in sight. The FIXED Roll holder makes your ride with your phone in the car more comfortable and safer than ever.
