We bought this item for a bike ride in Michigan. Traveling with GPS drains the batteries quickly and we wanted to be able to use it with my iPad mini 2 in addition to my iPhone 6s. It worked great on both devices and my iPad didn't slip when we rode cross country. One time we had to put the iPad in a plastic bag because of the rain and there were no slippage problems. I held the handles horizontally (left and right). I think if they were vertical (top and bottom) the iPad wouldn't be as secure. I think if the road was rough the weight of the iPad might cause the springs to "jump" a bit.
