Hey eveerybody. I purchased an external battery pack (hypermac) from this website. I chose this website because it said it shipped in 2-5 business days. However, this product was not recieved before my trip to India (a week from the day I ordered it). After coming home from a 2 week trip, I began researching this website. Most of the review were from enraged technos like me who had not recieved their product and were not refunded. I began to get scared but did not get the chance to call or email them. I felt I learned my lesson and it would be too hard to get my 300 dollars back. However, nearly almost 2 moths later, a mysterious Chinese package was delivered to my door! I opened it up, and there it was, in the official box! However I began to suspect that it was a knock off. The box said HyperJuice, not Hypermac. However I was relieved when I called Hypermac to confirm it was official. Don't badmouth this site, just be patient. But I won't be buying here again.
