Two months after the initial purchase, the bluetooth functionality stopped working entirely, and no other device can detect this gadget. The link was initially only temporarily severed, and later it was discovered that the signal had completely vanished. And do not return it under the terms of the warranty; there are no officials in my part of the country. Since the 1990s, everything of the Marshall gear I've used has performed flawlessly; therefore, I never in a million years would have guessed that the company's reputation would suffer to such an extent.
