Well I've been looking into their site some more and their return/refund policy matches miningdudes.com refund policy word for word.  Even to the point where hardwardia even says "If you complete a purchase and wish to cancel it, contact the Mining Dude’s RMA Department."

With that said, their description of products are also copy and pasted, this time from parallelminer.com.  In contrast to their refund policy of 7 days, their products mention that all sales are final and only accept cryptocurrencies.  However, if you go to checkout, you can use PayPal. Which would be nice if this place is legit and PayPal is accepted.

I get it that there are a lot of home businesses, I used to have one, but just keep in mind the address is a residential address.

I definitely like their prices and what looks like availability, but something seems off... Especially the fact they are copying and pasting and not even changing other company names.  
Hopefully I am just over thinking it


Heres a screen shot of their refund policy
