I am very excited by the device itself - it met all my expectations but beware !!!! the device that I bought directly from Amazon was branded: So you can not perform any firmware updates. I have realized this fact only after the purchase and I turned to Amazon: The answer was that if the device had been ungebrandet, this would have been in the item description. Normally this notice is but since then, when the device is branded and not vice versa. Interested Käuder should therefore be informed in advance.
