This is supposed to be the latest refresh of the G903. The one with 180hrs of battery life with RGB lights off. Fully charged this mouse has 32hours battery life. It seems this is not the latest version of the mouse but the older version with the crappy battery in it.
Confirmed the WRONG iteration of this product was shipped to me. You're charging for the NEW version of the G903 with a greater price but sending customers the old one. Awful experience. BUYERS BEWARE.
