I love it, so far. It has more of a "thock thock" sound, like a Topre, because the pang and click are reduced dramatically. It's very pleasant.
The tactility is still there, but it's not as "sharp", it's much more smooth than it was before the grease was applied.
I forgot to order a nozzle with my tube of silicon grease, so I just cut the tip off a Q tip and used the edge to spread the grease around the tubing of the keycap. I used a solid amount but I didn't load it down.
I'm enjoying the feel so far, it's extremely pleasant.
Also, my wife is much happier as well, since we share an office.
