Found one look same for iPad Pro 9.7inch but connect to any android and apple tablet and phone I've tested it with. Size of tablet that fits perfectly is 240mm by 170mm. Internal battery fitted but not sure how long it holds. Made from aluminium alloy. Wireless Bluetooth 4.0. Multicoloured backlight. Working fine some scratches here and there. Please take close look at photos and if you need more or have questions don't hesitate to contact me.
