I have been a few days the PSR 10,8 LI. for me this is the perfect compromise between a small and a much larger ixo PSR 18: small, light, easy to handle, often operational. due to the size and weight that is most versatile device on operational for DIY enthusiasts. the screw is more than enough power available, small holes, it was good enough, if it should be more power I reach the right drill.
the PSR 10.8 by the Li-Ion battery is always ready for use, self-discharge there is no longer so.
If the battery is empty, however, times: after about 3 hours hours full power is available again.
luggage included is not overly large, but perfectly adequate. a small jar with a few bits and drill bits fits more purely.
for me it's the perfect battery drill / screwdriver .....
