With what I write this review ... probably :-). Prima adapted keyboard, optimized for my SGTP5110 (Tab 2 10.1). Super flat and accurately, so that the keyboard barely brushing. With this keyboard (inexpensive) Tab 10.1 is go to a (nearly) full-fledged PC for train. Yet a little mouse to BT and it's perfect for work. Requires no drivers. The battery life I do not know because I have never loaded (thus appears to be a cross-country skiers). CONCLUSION: Cheap and works perfectly.
