Price / performance ratio okay, poor battery life

So the advantage is really great, connection is fast and constant. Charging time is a bit long, so I still have every 2nd day the tablet on the cable at my Intous 5 L must :( here a 2nd or third compartment for additional batteries would possibly have been great, S = 1 battery, M = 2, L = 3 ... place would have been there. 1150 mAh are, after all not much ... Every smartphone has almost twice as much, in approximately the same size.

* EDIT *
So the battery life is really bad, one day you can work without wires, to work on the next must with. So is more or less a back and forth. Those who do not depend on it every night, has the next day cable required! Even me all power-saving features, I use no LEDs on the Tablet and energy-saving function is activated after 1 minute.

Recommendations for the Intuos 5 L = cable instead of wireless. Use or tablet and mouse, wireless mouse, hold wesentich longer through. I personally like it just does not always grab back and forth.
How is the consumption of the smaller variants M and S, I do not know.
