The device was bought on a camping holiday and the same with a 4500 mAh Li-Polymer battery (no-name brand) supplemented. I would recommend the device only. Despite its compact Bauweis it has an excellent for this size volumösen sound. The reception characteristics are very good, which in Berlin but need not be a yardstick here, because here you hold a wet woolen thread in the air and gets 20 channels. In eastern Saxony, for example, with digital reception not to do what is not but the device because digital radio there have not yet been invented. But the normal, analog FM reception also is fine, of course noisier when one is digital spoiled. The many technical refinements I have not tried yet, except that rewind the message just heard what works fine .. I find these digital options and the associated additional information at any rate very well. The battery lasts extremely long. A little annoying, and by the developers m. E. no rhyme or reason as set up, but I think the fact that you can use when using battery power, neither the alarm nor the set time is retained. You always have to use the 220V power outlet, otherwise the device forgets immediately the set time. And this feature eats really no power, considering that the Mini-battery in an alarm clock keeps to 2 years and here a veritable powerhouse was installed in battery. For these "dropout" I deducted a star. But I would buy the device at any time and recommend it gladly. The Desin is incidentally also very appealing to my taste. The interface combines pleasantly how velvety rubber, so quite handy.
