I switched from g502 to 900. definitely worth it. but please don't get it any more than rm460 though.

no input lag and such, recommended by gamers nexus.

it lasts 2 days of long hour gaming if you set rgb cycle and 50% brightness. my g900 has never dropped below 30% battery before, to charge it fully after 2 days, you'll need around 1.5 hours.

also, it's not rubbery like g502.

lazada. there were sales that time. now i have no idea. try asking for best price whenever you shop in lowyat or IT shops like c-zone, jayacom etc.

g903 is exactly the same with g900 except for the optional weight like what's inside g502 and that fancy wireless charging (and costs a lot more because it's new).

I'd go for 900 but it's my preference. also, once you go g900/g903 you'll never look back.
