Delivery was prompt. The device is well described and can be easily put into operation. I have not worked much with it, but it seems to work well. Superfluous and thus verteuernd is the accessory that just lying around now. Also on the accus you could do without, because these are already available in general and wird.Ich just wanted a new, better charger had nevertheless decided to use this device, because the reviews and the functions described pledged me. The all too much vaunted flexibility would be appropriate here, and cheaper, that is cheaper!
