Blues and gaming cons:
1) Key has to be let back up further (fractions of a mm), before pressing it again, than blacks, reds, browns and clears.
2) If you're gaming at LAN or on a headset you can annoy you might tick off your team mates
3) They're light keys, so the heavier handed folks, could accidentally press a key, easier than with blacks, clears or buckling springs.
Pros:
1) You have auditory confirmation of when the key activated.
2) It is easier to feel when the key activates, than linear or brown switches.
3) You can tick off your enemies or competition. They need to learn to concentrate better.
4) They're good for typing
5) Less fatigue, than when typing with blacks/clears/higher force switches
Couldn't recommend this razer to stepmania player, because it doesn't state NKRO.
