I just got my Rexus G6 package delivered the other day. Despite all my excitement, it came with a flaw: something on the inside stuck and prevented the case to fully shut. And thanks to that gap, the left-click button didn’t function properly. For a while, I compromised by setting another button as the left-click button ( link ). But that got annoying pretty fast. Since I did not posses any patient to wait for replacement, I decided to open it up myself. First, unscrew the bottom of the mouse (the screw might be hidden under the warranty sticker). BEWARE THAT DOING THIS MIGHT VOID YOUR WARRANTY! And voila! It’s open. Since I only need to re-attach the case to its proper place, this is it for me. But for you tech savvy, the rest is up to you.
