(edit: feel free to comment, but pls avoid naming the label (err kay ess one hundred ...) to avoid getting indexed by google lol)
it was the best computer mouse in the world at one point, because it was the only computer mouse at one point. despite that it's kind of annoying to use because it's huge, not very economic, and it requires a surface with a lot of friction to roll the ball (my ultra slidy gaming mousepad doesn't work with it). the cable is also way too thick and cablemod doesn't have any replacement cables for it. right clicking is also hard because right clicking wasn't invented yet when they made it. it also doesn't have bluetooth, so i can only use it on a TR-440 mainframe and not my phone without a huge dongle, which kinda sucks. but at the end of the day you can move your cursor and click, so i can't complain. 5/10
