Product works great. The casing can be removed to access the board. Using a few pins and an arduino (or a CC debugger) it's pretty easy to flash custom firmware on the chip. I'm using it as a Zigbee router now. Note, the default firmware on this stick is the Texas Instruments Sniffer firmware.

Nice package for a CC2531. Headers are available, but tricky soldering.
