The product or rather the handling calls from a patient. In my case, however, the investment has paid off! I'm very satisfied. The manual is very chaotic. But when one is dealing with it now and then, to get to the goal. In a combination device that combines three in one, it needs, in my opinion, of course, more time to have all the features angetestet at least once. Recording and playback quality are right. Unwanted noise is also in short supply. I can write a conclusion with a clear conscience, the purchase worthwhile.
