I bought this keyboard for Teclast X98 Tablet 3G air, it fits perfectly. The color is the same, it seems that the two are sold together! The closure is very firm, no risk that the two stand out, but suddenly it takes a little practice to open easily. Ports and tablet buttons are still available, and Bluetooth connection is fast and stable. The keyboard is QWERTY, but some special characters (@, £, ..) are given the wrong keys, but you can easily find them in the usual location of a standard QWERTY keyboard.
Still not enough perspective to judge the battery.
