What the.....every device ,peripheral built can have manufacturing issues that dosnt mean that all the devices built are bad. There are scores of reviews and users who praise the X6 and many who had issues with it too. Its normal. And I explained the ghosting issue is inherent with membrane keyboards. Google and read. You will come out clear on that.
Its not a manufacturing issue with a few unit, its a hardware bug, and yes, while I can't press a dozen keys on a USB keyboard, but all gaming keyboards apply special anti ghosting methods, around wasd clusters, the ctrl buttons, space etc, the X6 has the issue if you press left ctrl it locks up the r key, so no reload while crouching, that's the death scenario in most shooters.
And in the last page.
even a gawd damn X6 owner said that X6 is useless for gaming, what more proof do you want? Do you own the X6?
which one is supposed to be more expensive ? X6 or X4.. if it is X6, X4 should be even cheaper no ? O_O
Logically X4 is cheaper, but you see, it has terrible ghosting issues and most people avoid it, they go for X4, so the demand is high for X4, hence overpriced, and the X6 is no longer sold, even if you could snag a unit its a stock clearance sell, hence the cheap price.
