I would ignore mouse reviews by hardwarecanucks.
I dont know what or who "guruverdict" is but considering their "top fps mice" doesnt list the fk, id say they are probably recycled clickbait.
If you want a review of a fps mouse, get it from people who understand fps.
I read some of that 10beasts page and like, every other word is wrong. The fact they list a fps mouse which vibrates should be a hint that they know nothing about fps games.
