Oh my.... Currently typing with my Ninja brown switch. I love side printed keycaps. My friend look from side and top position and they ask me why buy a keyboard without legend.

Well, Ninja are hidden, and mysterious. I agree when from other position other than bottom, the legend are hidden. It's not a necessary feature, but it's unique.
And the stock keycaps have matte finishing. I love the sensation. Just like rubbing lace panty...

So far stock keycaps are easier to removed than my old Ducky stock keycaps. I was so afraid that I damaged my keyboard while removing my previous keycaps last time.
Filco brown switch sensation are different. It's like touching a soft but bouncy boobs.

The bottoming sound aren't loud as Ducky. I didn't need to press so hard on Filco thus so the bottoming aren't that loud. While with my previous keyboard, the switch are not really soft as Filco. So I need to press harder and that's mean louder bottoming sound.
Maybe it's due to the pcb, frame or keycaps but Ninja really suit the name. The most obvious pleasure is when I press the modifier key. I don't know how to explain but it's totally different than my last keyboard.
The wight are, I don't know. It felt solid! I think I can bring this keyboard for a gang fight and give "keyboard slap" to some guy. Can anyone confirm me if Filco height are lower than Ducky? I'm not sure but it's look like the frame are thinner. And it's more comfy when typing. I think wrist rest will give more comfy for typing experience.
And I love the included key caps puller. Well, it's wired, so it's not fair to compare with some plastic keycaps puller. And maybe one of the reason I felt less secure while removing Ducky keycaps is due to the puller.
And the price? It's RM 33x as stated at Edifier sell thread.

Which is really worth it for the pleasure she gave me and she kinda highly praised (based on my observation) among old time mech kb enthusiast.
The downside of this keyboard, I'm frustrated to see fixed USB cable. Well, I'm somehow poisoned with sleeved USB cable by some forumer. Another thing is missing media key. Well, media key can be useful in some situation especially in next or previous track with Foobar while finishing some office task. And yeah, no backlight. Well, to be honest with or without backlight are the same for me. Because even with backlight on, I do a lot of typo error too. Hehe.... And I regret for getting brown switch. I should have take blue switch. Well, it's not Filco fault but it's my brain to blame.
And I'm not saying that Filco are better than Ducky
but in my experience, Filco felt better than Ducky. Well, it's Shine 1 and I read somehow that latest Ducky QC are better than my previous Ducky. So it's not fair for me to said that Filco are better than Ducky. I'm looking forward to try Ducky Shine 3 when they released. Ducky owner, please don't attack me.

Plus, so far I only owned two keyboards. So my experience are not enough for me to critique other brand.
And I didn't realize I type such a longgg post. Well, time for me to go out for a drink. Cheers!
