In general I am satisfied with the purchase. The house was set up with X10 controllable lighting and wanted to link our Echo to control it with voice commands. I have a FireCracker CM17A lying around, but it's a serial device. Most computers no longer have these ports. Tried USB to serial adapter but it didn't work. So got this one. Worked like a charm out of the box. Alexa can now control our X10 modules! The range was a small issue. just moved the RF receiver module to a closer outlet.
