The UM560 was my first device, the one I actually purchased.

The NAB6 was the one they took forever to send me as a replacement. It died within a week.

Getting my UM560 replaced took ~50 emails.

They tried to charge me the difference between units even though I was under warranty. It wasn’t my fault they didn’t have any more UM560s.

Then they tried to charge me a “depreciation charge”.

I won’t do business with them again after their horrible customer service.
