No, it's not a resale; it's a Chinese company going into business with a US front company. It's the KK-MINI Smart Plug made by Inspiring Corporation of Wenzhou, Zhejiang, China. I spotted this through reading the app page, but the definitive proof is the FCC registration for IntelliPlug. Observe the managing director is Robert Shan, and we see a Robert Shan on the IGG team "based out of Asia".

Their web site only lists this as "developing", but they have showed it at the Hong Kong Electronic Fair. BTW, their other Smart Plug, KK-SP3, was sold for a while as Amcrest Connect AH357, but Amcrest (a Texas company) have dropped it now.

So, it's a legit product, they're just a little cagey about where it really comes from. But all consumer electronics is manufactured in China anyway, isn't it? :-/ Even if sold by a Texas company under their brand.
