This is a good addition to anybody's toolbox. It feels nice quality and comes in a sturdy handheld case. It is quick to charge - roughly about an hour on my first use - but do be aware that you will need a UK adapter. It has a 12V Max motor which delivers up to 30 ft-lbs of torque. It's coped well with the use I've had so far. I wouldn't recommend it for bolts that have seized though. You would need a breaker bar for that in my opinion, but this is powerful and so convenient. It's great for speed or just making life a little bit easier. It's amazingly handy.
The whole kit includes 1pc charger, 1pc plectrum, 1pc storage box, 1pc battery and 16pcs wrench sockets, so it makes an efficient piece of kit. You will not regret buying it. Thoroughly recommended.
