I just bought it from LingLoong..
But I don't really like it.....
It's not suitable for fast typing..

Sometimes when I press spacebar softly (and fast), it register double space; or sometimes doesn't register the press at all..

So I went to http://www.microsoft.com/appliedsciences/c...gExplained.aspx to test this keyboard..

When I didn't fully press the key (any key, not just spacebar), it won't register the keypress or sometimes the key on that site went green on a blink..... but when I press the key very hard, it will stay green.. which I believe it means this keyboard only properly register the keypress when I fully press the key or when I press it harder..

While typing this post, there's a few double space occur.. but when I preview the post, there's no double space shown probably because of this forum automatically remove it..

And just now I found the same issue raised by other user http://logitech.lithium.com/t5/G-Series-Ga...ing/td-p/590818
