The Shaka switch was recommended to me after I expressed interest in the Anubis switch. It was described as a switch with an Anubis-level tactility with a better return, and when the switch came in, the description was spot-on.
This is a strong--but not overwhelming--hyper-tactile switch with basically no pre-travel and less than a mm of post-travel. The factory oil is light, but evenly spread, making these switches great to use stock.
The only suggestion I have is lubing the back of the switch leaf and maybe the spring base, as I hear some slight leaf or spring noise(but this is when I hold the switch up to my ear).
Great tactile, great value, and great pickup!
