egrandbuy and raidentech both used to sell on ebay. Egrandbuy managed to accumulate 84 negative and 59 neutral feedbacks in their last 6 months. Many of the negative comments had to do with poor communication and problems with the product.

From comparing the contact information, it appears the same people are behind both comanies. It appears they decided to shed their less than stellar auction past by creating at least one new id. I won an auction from a new seller. When the box showed up, the shipping label was from none other than Raidentech. In all fairness, I will say that the item was well packed, as described, and shipped quickly.

These are just some of my observations, I'll leave it as an exercise for the reader to decide what to do with this information.
