Kono 84

[bkrownd]

  I got a couple Kono 84 for spares, switch testing, experimentation and keycap display.  I could do without the wireless and RGB, but they come in my favorite layout/format and the price is nice.  They are pretty basic, with crisp simple lines and choice of basic black and white.  I had to flatten the slightly-upturned corner of the plate on one of mine, but it bent into place easily with careful pressure.  I haven't tried opening them up at all.  Switches seem pretty secure.  Stabilizers sound like they'll be rattly - are there simple options for impoving the stabs?

I've heard good things about the tailor's mod, simple, just time consuming. There's also the holee and plumbers mods. Other than that, your usual lubing, and clipping.  I don't recommend bandaid modding, as it can make your bottom out mushy.

Something people forget to consider is stem wobble, a switch with great stem wobble will have significantly less chance of rattling. 
My NK65EE’s plate mount stabs with U4T feel non existent, a Durock linear sample I got have phenomenal stem stability and really reduced non-properly modded PCB mount stabs on a board I have.
