It seems my latest batch of B2000 badges are having a lot more issues than the older B1000A's.  I have many badges that have only be in service a couple of weeks with bad DNDs, blank display screens, or powering off after a short period.  It seems I never had this many issues with the B1000's.  I'm afraid to buy anymore until issues are resolved.

The microphones on the B2000s also seem a lot more sensative than the 1000's.  Background noise seems to adversely effect these much more.
