It's moderately scratchy and moderately wobbly (kinda comparable to MX switches I have, may be tad more. Comparable to model F, actually).
It doesn't bind.
It doesn't click either. I mean it clicks outside of the barrel. It clicks when key is all the way down and flipper disturbed. The spring resets when key gets back up. It just doesn't click when fully assembled. Key travel is 3.8mm - but actuation is somehow even lower.
PS: Noticed a weird thing: assembled model F actuates at around 2mm travel, and original parts assembled on the table at around 3. Turns out, it does matter how spring is mounted: mounting spring in a correct position (see Fig. 1) produces initial incline (see Fig. 2) of about 5 degrees, which - together with initial ~2.5mm of compression pre-bends the spring, setting the direction of future buckling, as well as dictating it's future direction.
Interestingly, Brother flavor of buckling spring is mounted strictly vertically. And they buckle at ~3mm! Except Brother pre-compresses their spring 1mm more (and key stem end actually stops ~0.5mm below the flipper's bottom!) - so I'm kinda lucky my "improperly mounted model F" buckes at 3mm.
Also, Brother springs are essentially model M - so it looks like that extra 15 grams of force are coming solely from that extra 1mm of spring compression!
