so, i needed a new mouse. my wireless one seems to have become worse over time. it would connect, but it just wouldn't track across a surface right, and it kind of didn't even matter how pristine that surface was. M510. became frustrating and annoying well over a year ago but i've lived with it and traveled with 2 mice (one a wired gaming one) and 2 laptops, would swap the wired when i really wanted to.
went searching around for what's good, and they still even sell that M510. but enter the mx master - this thing is awesome! i haven't tried it, but it has angled beam/sensors so it's even supposed to work on glass. up to 1600 dpi. it's worked perfectly on everything i've put it on thus far. you can bluetooth synch it to up to 3 computers and just switch with a button on the bottom. it has a thumb scroll for editing photos or videos and scrolling side to side. feels good. thumb pad is actually a button too.
but my favorito is this wheel. it has a button on it to put it in let it rip free/fast scroll mode, or the normal geared mode. but here's the best part - you can just whip the wheel while in geared mode and it will switch over to the latter, then return to gear mode. it's awesome. no scrolling then deciding aw fuck it you really need to grab that side bar - if you're working in something with a lot of rows like excel or some source code, you can just throw that fucker down and spin freely until you want more precise movement. it's awesome. i highly recommend.
