CST Ergo Wireless Mouse

I think that is wired, this one is wireless

Those of you arguing about the price should be aware of this: the cheaper versions are from Delux, and this is from CST. The difference? A logo. Can Massdrop be blamed for CST selling a rebranded item at a higher price? The last time they tried a drop for the wired version, the same conversation came up. I went straight to eBay and bought the Delux one shipped from China for much cheaper then. So yes, if that's how you feel then do that. Do we really need dozens of people saying the same thing? One person says the information that others can read, and we all move on our way from this drop. Or people who don't read the discussion can fall right in. As far as the software side of things, the Delux ones work just fine with CST's Superior-X software.
