No use! I said to myself, others are perhaps good for nothing, they tested bizarre touch, but made no they were right, so I used on my Nokia Lumia 920, and as expected ... useless! Even for micro-scratches, I assure you, those who say that it works for them, it's the placebo effect! I handed the tab I refrotté as a crazy, nothing !!!! How can we dare to make and sell something that does not work ??? !!!
