Two days later the replacement unit was already on its way to me (5 Stars). Even the postage was print email me link saves return form by computer. I can only say: The Abel Service is first class. I also know other providers that are not recommended. For device: Now you have to be aware that it is not the upper price range and therefore also of the operation could go a lot easier. Edision but always working on improvements and makes them available to users. So I can say that the value for money is absolutely OK.
