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 got some from Taobao recently and they were pre-lubed. The factory lube job is the best of any switches that I've gotten to date. It's very good. They're a tiny bit sluggish out of the box, but that dissapears pretty quickly with use.
I’m still somewhat new to the whole custom keyboard market, and I’m unsure as to wether these are MX style stems or not. Could someone clarify what these are and the differences?
They are MX. The cross shape at the top of the stem, the shape of the plastic housing, and the pin layout on the underside is what makes them MX. Other switch types come in a variety of stem shapes, housing shapes, and pin layouts.
These switches are 5 pin. Even if you have a 3 pin PCB, you can always use nail clippers, or plastic cutters to clip off the extra plastic pins (Do NOT cut off the metal pins, or the switch will not function)
