This product is a real plus for the owner of Samsung S4, bringing an additional function at the same time it protects the glass effectively. A quick tour of the settings and your calls or alarms are displayed in the small window. For the seller, TheTechTree.uk, 5 stars, too, because the delivery time was much lower than that advertised. I think they are afraid of the Channel crossing time and take a little margin. I received the product two days after shipment.
