I am a big boy and I like heavy switches. As a linear gang member they are perfect, smooth pretty and for now reliable. The lube is okay. I recommend putting them into a keyboard (if it is hotswap) and then just applying more lube if certain switches need it.
Hoooooooooly cow these are smooth. Like smoother than smooth. You think Durock linears are smooth? You ain't felt smooth. Slap some of these bad boys into your board and prepare for a linear experience unlike anything else. Mine were even perfectly factory lubed and the housing tolerances were perfect, meaning you don't have to do any extra work to them. They're totally stock, and they're totally sick.
I 'm glad I bought these Aqua King's. I lightly applied lube on top of the existing factory application focusing on evening the distribution, and I bag-lubed the springs. I'm going to say it: they are like Oil King's that let the light shine through. Is it accurate? Of course not, but it's the best compromise I've found so far.
My fingers are happier with the Aqua King's because when I look down, I see my beautiful keyboard shining like a device worthy of obsessive tedium and the occasional squee from nerdy me.
They felt a tiny bit scratchy before I lubed, but now they are freaking awesome, man. So good, I regressed to talking like it's the 80s. Don't hate me because I'm corny. I'm just a girl on a keyboard with a huge grin and an emptier wallet.
