I did buy a Dell Raid controller card from this company via ebay, when we instaled it, we realised that it was not working, we then requested to send the item back to be exchanged or refund. we sent it back, never heard from them again. I don't know what's the deal with ebay and paypal but they simply keep ruling this transaction in favor of this people, I did as they instructed me, sent the item back with the shipping label they privided me, tracking number 420110239302020128700430155516, they have received it, i just know that i lost US$ 250.00 had to buy another card in a rush, sent several messages to this people and never heard a single response. in my opinion they are scamers, they probably sold the same defective item to another person and they are probably in a limbo just like me.
