This worked fine while it worked and took almost a year before the GFCI socket stopped failing. After resetting the switch, GFCI socket and powering it back on, the unit arced (clearly visible in this video) and smoked inside the unit. The exterior was also charred around the sockets on the cord. The cable appears to be durable and suitable for regular use, but unfortunately this type of issue is causing me to look for a more reliable and safer product.
