hey guys, just curious if anyone knows the difference between a real authentic Blazer GB2001 from amazon or eBay or a knock off from dhgate for less than a 1/4 of the price. I've had a couple of the knock offs and they were perfectly fine, but i'm just wondering if an authentic would be better in any way to justify the cost? I need a couple of them so $20 vs $80 makes a difference. thanks!
