Cherry MX Blue Keyswitch - MX1A-E1NN (Tactile Click) - Plate Mounted
Product Review (submitted on February 24, 2015):
I bought 4 keys because I spilled tea on my current cmstorm mechanical keyboard. I thought it was over and I would have to buy a brand new one for around $150. Found this site, re-soldered them in for ~10 bucks. Saved myself a ton of money and extremely happy with the results.
