I received the toughened glass with a big surprise. In fact the glass is consistent with the description: fine, robust, easy to install! The installation requires no special attention if not properly it just takes align the tablet screen, and let it flow like water on the surface of the screen, it acts alone! Once landed, the result is stunning! The surface is smooth, pleasant to the touch, little trace of the fingers retained, at least for now. However for the price I bought the tablet, I find it a bit expensive ie almost 10% of the shelf price!
