Recently placed an order through these guys, and was extremely hesitant. They had a couple of things I couldn't get elsewhere, so it was a necessary evil. Surprisingly, everything went smooth. My only issue was the shipping/processing time as slower than I would have liked. Got everything I ordered, the King arms Hop Up was even fully assembled, but I suspect this was from King Arms rather than evike.
While my order was good, I would still be hesitant in the future. Far to many people have had issues with their service.
It may be worth nothing that evike is now known as airsoftpost.com when I post this.
