Package arrived very quickly. The product was very well packaged. On arrival the keyboard battery is not charged. However, it can be used during charging and thus test its effectiveness very quickly. The association with the tablet is simple: Bluetooth is activated on both devices, pressing the Connect button on the keyboard, the tablet then gives us a code to type on the keyboard and voila! Simple and effective. The tablet fits comfortably on the keyboard, either horizontally or vertically. The attachments appear solid. The hull is effective when used in protection. It regrets the lack of rear protection. At first I do not see how the couple with another case. The keyboard itself is quite nice. It takes some time to get used to his size. Attention, it is not a silent keyboard. We are not facing an extremely noisy keyboard, but it is far from a silicone keyboard. One senses the hull vibrate typing for limiting this presentation and caused noise, raise the hold at the rear of the hull is quite effective. Regarding compatibility key one is almost all good. The shortcut keys work and are significant. As someone else said the AltGr key is present (gr simply is not registered). But beware: this button does not work with all apps. If on chrome, google docs and gmail there is no problem, Polaris will not accept him. It is therefore not possible to make certain characters with the keyboard directly on this Application (and possibly others).
