This product works nicely and is very well constructed. The Web interface is rudimentary but effective. Although I have not used it, the Android interface appears a bit more user friendly. Note that the unit always powers up in the "relay off" state (you cannot save the relay state). The construction is high quality double sided SMT and the plastic case very nicely constructed with brass bushings for the screws.
I am using one these to provide "ping monitoring/reboot" on the motherboard for an access control system, and have just ordered four more for use in process control in a manufacturing facility. The quality and functionality for the price definitely rates 5 stars.
As a final note, BrickElectric provides exceptional customer service.
