    Thanks for this review and details. I just bought one and I am surprised by the built quality – taking it apart is interesting and shows great attention to details – I will eventually flash it with Tasmota but, for now, I don't really see the advantage. The power measuring feature is quite impressive.

    Interesting information to see S/H + imports fee to Bermuda cost more than the unit, by itself.
    You can also get the unit to a cheaper price from Ebay and wait forever to get it.
