i just brought G700 for RM270 in Midvalley.
For what i feared about mouse issue on wireless. i kept trying all types of pooling, and repeat rate, battery power mode, it doesn't seems to suffer any type of problem as stated in their website.
So i think this is wireless issue, but hardware based error, but if anyone that brought the mouse really suffer this issue, i suggest you may go to RMA your mouse.
For me, this mouse just feels very good, and all the settings seems convenient and nice, i really appreciated for purchasing an awesome mouse just for RM 300 below.
and the mouse feels just comfortable in my hand, more better than the gigabyte that i`m holding(for me, because i got slightly big hands.) i tried palm grip, my hand is still slightly bigger than the mouse. i will may go for palm/claw grip hybrid

. But the mouse is really comfortable for me, if made compare with GM-M8000X, i don't really like the mouse design a bit, because of the thumb area, quite bend to the inside. and both side rubber with holes... you may have alot of dirty stuck in those holes. Well. currently still not yet written the review.

.
i would rate G700, 4.5/5
The only complaint I have is the stiff charging cable. Not easy to move around with it attaching the mouse.
