Review on Black PERIMICE-720 Wireless Ergonomic Trackball Mouse With Adjustable Angle By Perixx - Boost Your Productivity by Eric Owens

I have had this mouse for a week or two now. It is my first mouse of this style. I am overall slightly satisfied with it, but it is not perfect. It lacks most in precision and in its uncertain bluetooth connectivity with older Windows PCs.Pros: This mouse is a lot more comfortable and satisfying to use than a traditional mouse. It is especially good for tight spaces and for long periods of use. It's back and forward buttons, scroll wheel, and center button are all handy. For me, the center button automatically functions to swap between your current and last used application (on Windows this would be the equivalent of using alt+tab). This was an unexpected bonus for me. There are two attachments that allow you to choose the angle you want to work the mouse at. These snap on and off easily using internal magnets, but they do cover up the on/off button, so must be removed whenever you want to access those buttons. I like the shorter attachment of the two. For some the choice between low and high dpi may be a pro, but for me I found the high dpi setting caused me to miss clicking on things so I stuck with low. 2.4ghz connection is solid and responsive.Cons: My main complaint would be that the pointing accuracy does not seem as good as a traditional mouse. It will take some getting used to, and maybe that's my real problem, but for things like photo editing or even detailed audio/music editing, a traditional mouse seems more precise. I'm taking comfort, bonus functions and compactness over occasional frustration at accidently clicking on something I didn't mean to. Worth it to me for now, but maybe not for some. Package lacks clear instructions on how to set up and connect the mouse. It took longer than it should have. I also was not able to connect the Bluetooth to my 8 year old Dell XPS 15 laptop with an upgraded wifi/Bluetooth card. I did connect the mouse to my phone's bluetooth successfully though, so it is probably my laptop. Other devices like wireless keyboards pair fine with my laptop though so I think the blame could be on both sides. The 2.4ghz receiver works great and I will just use that until I upgrade my laptop.Recommendation: I would recommend most it if you really want this style of mouse, need wireless, have a tight space, want something pretty comfortable to use with extra functions, have a device with updated Bluetooth specs (if you want to use the Bluetooth and avoid using up a USB port) and if you don't mind a little bit less precision than a standard mouse.
