The g700s, a flagship £90 mouse I bought back in 2013, is finally giving up the ghost. It's been fantastic. Specifically, it's wide, ergonomic, tall humped back, large thumb rest area, slightly matted surfaces, removable AA battery, unlockable scroll wheel, sensitivity profiles. If I could buy another g700s I probably would but they're all a bit old at this point. Logitech's new lineup is dauntingly populated, there are about 6 different models that look similar to this, and I'm in the dark completely with other brands. Anyone got any recommendations?
