2 times total failure UPDATE: direct contact with ANSMANN Update2: Now everything is good

A device what I wanted to recommend me for the second time denied the service.
I've even used about 1-3 week to AA / AAA / 9V blocks to load. The first purchased in 11/2011 was broken in 06/2012 after about 7 months. Total failure, none of the LED came on. Now, after the device has been exchanged for a new joined the defective after approximately 10 months back. Unfortunately I can not therefore recommend this product and I'm going to find a new device. Unfortunately, the name Ansmann does not seem to stand for the quality, which I had hoped in this case.

Update:
Commenting on my 1-Star rating reported to me Mrs. Muller from Ansmann AG, which was very helpful regarding my problem. So a new charger from the current production has now been sent to me, which has been tested in advance again, to send even a small reparations and the return postage to my faulty charger to Ansmann.

Ms. Müller explained to me about it at the beginning of 2011 came from my charger (engraving on the back of the charger), and it has now been changes.

Now I hope that as confirmed by Mrs Müller, changes in production have been introduced and the new charger works for years. For this great service, I thank you personally with Mrs. Müller and forgive time being 4 star with a tendency to 5 stars if I stay with my charger happy one year.

Update 2014:
I can now recognize the device the 5th star because there were no more, and it loads and loads and loads failures since the last update. :-)
