Bluetake BT007EX (USB dongle)

With the hassle bluetooth devices can give this has one been pretty good on whole. Initially there was some problems with the Toshiba software giving error messages after returning from sleep mode. After some feedback to Bluetake about some problems they gave a software upgrade to Toshiba stack 4.2007c. Much more reliable since but still occasionally requires removal and replacement of the dongle to 'reset' the software and it struggles with different user accounts being logged on simultaneously.

Generally it's been pretty reliable and I'd buy from Bluetake again.
