I bought this to play FF, but ended up not playing it, so it's new and unopened. It's currently around 21,000 yen on Amazon, so I think you can buy it cheaper here. The AEROX 9 WIRELESS, with its ultra-lightweight design and 10 programmable buttons, is perfect for MMO/MOBA gaming. 【Efficiently unleash your skills】You can assign various actions to up to 9 buttons. Ideal for playing MOBA games like LOL, and MMORPGs like FF14 and ELDEN RING. 【Only 74g despite having many buttons】Ultra-lightweight design that won't make you feel tired even after playing for a long time. 【180 hours of battery life】No need to worry about running out of battery even during long play sessions. 【40 hours of operation with just 15 minutes of charging】Supports USB-C fast charging. You can also play while charging. 【Safe and secure splash-proof and dust-proof design】Honeycomb structure, but won't break in case of sudden accidents (IP54 standard compliant).
