Defect after normal use - quickly overloaded

To start with the screwdriver felt wertig that I could have rarely check as he usually dusty in the closet.
I have been given him Christmas 2011 and can only use sporadically.
He made a strong impression and fits comfortably in your hand.
A bit annoying is that the LED only lights up when the motor rotates but that bothers me less.

Now it happened that I had to use it regularly for three weeks to screw screw tight & loose again. First, I noticed that after a few screws, the battery was weaker - have then charged him daily.

After maybe 30-50 screws I probably want something to tighten a. When lots of turning previously screwed screws he made always unhealthy clicking noises. Now when tightening a loud "crack" and now he no longer revolves - as another reviewer also I suspect to weak gears.

The support is fast - even though the page is structured very confusing. But have found the contact form (select only on the FAQ a question, then down "they want us to contact" or something like that).
Have even after less than 24 hours following response:
"Dear Mr. R.,
unfortunately I can here no guarantee / goodwill longer grant device's been too long out of warranty.
MfG
BK "

Shame
