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.
Out of 110 switches, had just about enough that were acceptable to use in my 75% build as some switch's stems would stick to the top housing on the return stroke.
Otherwise, they are very smooth after also opening and touching up the factory lube job.
They are great the only reason it's not getting 5 stars is because most of them for me came with a bad lube job. A lot of them were "farty" and unfortunately I had to open them all up and clean up before doing a pass again on lube.
