These have super tight tolerances. No rattle at all when lubed. However... Because those tolerances are so tight, if there's any manufacturing defects, a microscopically bent wire, a barely misformed stem or housing, the entire stabilizer will fail. They'll get stuck, not return, or not even assemble properly. So, these are great; provided yours are absolutely perfect.
Hit or miss it would seem
I've got to agree with the reviewer Jenneke here. The stabs are great in terms of having zero rattle (just 205g0 and you're good to go), but they seem hit or miss. Maybe I just got a bad batch, but I ran into issues with keycaps not returning using these. Everything worked fine when testing on just the PCB, but as soon as I added a plate the stabs would return slowly or not at all, and I tried it with different switches/keycaps to be sure. Just extremely tight tolerances all around. I used these on a KBD67 Lite for reference. If you have issues with these as well I would definitely recommend TX stabs. Those are wonderful if you're okay with clip-ins and I've personally not experienced such issues with them.
If you have a 1.6mm pcb without flex cuts around the stab holes, these are the ones. I put on some xht-bdz and there is absolutely no unwanted sound coming from the stabs. This should be the standard of stabs in 2022, TX are nowhere near.
Endgame Stabs, period!
These stabs provide super tight housing, giving it completely no rattle whatsoever. Wires are balanced right off the box, no rebalance required. Just add lube on the housing and on the wires and you are good to go!
These stabilizers need little to no tweaking
Staebies have well earned their reputation as one of the best stabilizers on the market. Tolerances between the housing and mounts are very tight, and wires were well balanced out of the box. Having used Durock V2 and Owlabs screw-in stabilizers - both of which are fantastic in their own right - I can confidently say Staebies offer the best stabilizer experience with the least amount of effort. As the other reviews state, all it takes is lubing the inside of the housing, the mounts, and the wire where it inserts into the mounts. No holee mod or clipping required, though you may wish to use stabilizer pads or band-aid mod between the stabilizer housing and PCB. Take note that the included screws are not standard Phillips head; you'll need a 1.5 mm Allen key to be able to tighten them.
