I found the G502 not wide enough for my hand caused some cramping after long gaming sessions. Its a pretty narrow mouse for my average sized hands.
Ended up giving the G502 to my gf and getting the Mionix Naos 8200 (found for $70USD on amazon)
G502 was a fine mouse though and would have kept it if it was wider would recommend you try it out before you buy if you can.
