I've used Otter Box for my cells over time..I love the Otter. Works as advertised. So I opened the Z10 Otter Box package the other day and wrapped up the Z10 in it. To my dismay, the high ridges the Otter has around the perimeter of the Z10 almost entirely prevent effective swiping of the screen. Whereas I had been able to change screens with one quick swipe before, it was taking 8-10 tries to make the same thing happen while the Otter was on it. I finally removed it to make certain there wasn't something else causing the problem, but once it was gone, the swiping became almost effortless again. Just saying...you might give it a try before buying.
