wah tq for this thread,
my g602 was having problem with its left button so i just retired it in its box. then i see some youtube about repairing it and i diy repair. Ops success.left button click was fixed!

but then it get into another error. the cursor cant move, all other button working. its seem like the laser sensor is broken. do some connectivity test with downloaded software from Logitech, it says it cant connect. then i check Logitechwebsite for warranty, i still have warranty.

i call them up, and they ask me to send the unit for inspection.

later i will update once i sent the unit for rma.

well there is no other choice, so have to be patience and bear with it...hope my case will be smooth..

ok now my update on my RMA,

well i didnt have time to go and send my logitech g602 mouse to MCL but one day i did it on 15/07/16 and was told it might take 1 week.
i sign the document and left my mouse there.
Bear in mind that i did rip open the mouse to repair the double clicky problem before so the gliding pad is in horrible condtion ( i did not glue it back properly)

since i already have replacement mouse, i didnt bother about it.

then on monday 01/08016 i call and they say its ready for pickup.
today i go and
walla,
i got a brand new g602

tq

even u rma, the warranty period does not change even they give u new unit. but i think wthin the warranty period u can rma many time.

well i just call em and tell that my mouse cant be detected.
then they ask to drop the item at their office in subang/summit.
then i go, drop the mouse, they tell me it might take a week.
and they will call back to notify plus they give me the technician phone number.

didnt bother to answer unknown number and lastly i call the office, tehy tell me to come to pick up new rma unit.
