Was having a little bit of latency issues with my Razer Basilisk X Hyperspeed wireless mouse so I decided to go Wired. Read a few reviews on this and noticed it was special so bought it.
So far it has been extremely smooth and comfortable. It is a little larger than my previous mouse but fits my hand very well. I have a finger to pinkie span of about 225mm. If you have less than 200mm span I don't think this mouse would feel very fluid and natural for you.
