I tried AAAA batteries instead of AAA on my new Rival 3 and they fit. I didn't even have to use tin foil, they stay put. They are much lighter than AAA batteries and my mouse is lighter now, and if I use only one AAAA it's even lighter.
The Aerox haven't arrived in Asian countries sadly. The rival 3 wireless is so nice, but as someone with large hands, I'm afraid of getting it and not liking it. :(
Hey Dude, I got the Aerox 3, it's like the Sensei 310 BUT ...a bit too small for big hands, ...but if you are like me, you should buy the Sensei 310, it's VERY comfortable for big hands and very precise! I wish it would be wireless, I would never switch then.
