This is a scam. If you look on google maps at this address there is a beauty shop.

Greetings,
And thank you. If you look closely at the map, you'll see a huge warehouse located in the ISO Beauty Professional building. We are the Master Distributor of Gridseed for the United States, Europe and Hong Kong. Please contact sales@gridseed to verify the claim.
