Well that's good to know, it sounds more like a slight design flaw due to how those two keys are laid out, although some boards might have full brightness there... It doesn't bother me too much, it is just that I paid a good amount of $ for the keyboard and if pretty much everyone else had equal brightness across all the keys, I would want my full money's worth.
It mostly just has to do with how the LEDs are laid out in relation to the switches themselves. When you pop the keys off you might notice that the characters on the number keys and the commands on the numpad are also fainter, simply because the switch itself blocks a portion of the light. Ditto with the numpad plus sign and enter key, the switch physically blocks a portion of the light. Personally, it doesn't bother me in the least, but I can certainly see how it might bother some. There may very well be a way to hack something in order to have the LED fully light the key... the upside being, you only need to do so for keys with a secondary function, the downside being that I have no idea how one would do that since you have a very limited amount of real estate to work with and it's still a lot of keys.
On an unrelated note, I received mine from TigerImports today, and Cherry browns were the perfect call. It's a bit of an adjustment coming from my previous keyboard (a ****ty backup rubber dome keyboard), but I enjoy typing on it, I love the clicky feedback. Definitely requires more force, but I guess I have more manly fingers, and don't see it as an obstacle at all. Definitely happy with this as my first (well, first since an old Dell years and years ago) mechanical. I'll take it through some gaming tomorrow to see how it holds up, but so far so good on the typing. Only complaint is the price point (but I'm warming to that a bit) and the Engrish instructions (but I figured most of them out). Also the little duck guy on the space bar is a cheerful little exception to my normal hatred of branding.
Also, I like that they included a dust tray. I've seen what can come out of a keyboard. Ew.
