Pifco is a classic British electrical brand that used to make things like vibratory massage devices and Christmas lights. I'm not sure who owns the brand now. The design of the module in this is good. It has signs that the person who designed it was aiming for good electrical separation, and it does use a gas discharge tube for extra isolation on the earth/ground connection, and has decent MOVs (Metal Oxide Varistors) or VDRs (Voltage Dependent Resistors.) It also has a sensible power/protection indicator that should last a long time.
