It IS perfect!
I usually don't write reviews but these are so smooth and perfect I wanted to type something. Two thumbs way up!
Only used a light coat of BDZ where you would still see the wire parts through the lube. And there was no rattle for the most part, and only needed to apply more on the spacebar.
Unreal how smooth and rattle-free these are!
I put a light coat of Glorious G-Lube (it's what I had around) on the stems and bottom of the housings and these stabilizers do not rattle AT ALL with no mods whatsoever. So I'd say they're indeed almost perfect if not perfect! I did not use the stoppers and I've had no issues so far. I'll definitely be buying more sets for my other keyboards.
TX AP Stabs Rev 4
These are great. Gave them a try after being less than thrilled with the WS stabs that came with my Zoom TKL. A bit finicky to get the stoppers in the clip-in leg on the underside of the PCB once installed, but once you've done that (if you even choose not, not sure it's explicitly required) these are super great. Light 205G0 on the housings and stems, dielectric grease on the ends of the wire- good to go. Very little tuning required.
They are good once you get them in. I didn’t test them unlubed, but lubed they sound good. The one problem I had was that on a few(2 I think) the housing wouldn’t snap in a stay down, it would push back up off the pcb. Not sure if this was a me issue or a stab issue but it was super annoying and frustrating, and they were unusable. Luckily I didn’t need the extra.
