I bought these to use with Tasmota and they work great! Easy to disassemble with a screwdriver and a plastic spatula, easy to solder in places clearly marked for programming, and not scratched at all after disassembly. The Tasmota software can even see Power Factor, Watts, Apparent Power, Volts and Amps! I haven't tried the included app, it probably sucks like most smart plug apps.
