Review on 🖱️ Enhance Efficiency with Kensington Pro Fit Ergo Vertical Wireless Trackball (K75326WW) by Jerardo Phi

I drive a CADD car for work and switched to trackball mice a few years ago. The lack of a string to move the mouse when I let go was its main selling point. Thumb trackballs give me a lot less hand fatigue than finger balls, so I prefer them as another company made such a ball a few years ago. After this company had quality and warranty issues, I started looking for an alternative. Kensington was the first place I looked. I wanted some programmable buttons (CHECK), a thumbball (CHECK), a wireless BlueTooth or dongle connection (DOUBLE CHECK!), and ergonomic mice intrigued me (CHECK). The Kensington PRO Fit has 9 (!) buttons on the top for use and 3 on the bottom for functions. What a mouse! With available software, you can program them for functions, keystrokes, shortcut keys, and program access. You can even customize the buttons to perform different functions for different programs. The ergonomics and thumb-operated ball keep your hand in a normal, comfortable position on the mouse, although I notice I still tend to press the button directly. Table for pressing buttons. I had to turn off the scroll wheel for the correct function as I kept activating it over and over again by mistake. (I don't need it anyway, so.) I've also found that my hand is less prone to cold compared to mice with a "normal" orientation. There are two ways to connect to the computer: Dongle or Bluetooth and Bluetooth. This allows you to connect to 2 different devices. You can connect to a computer via a dongle, to a phone via Bluetooth (it works. Weird) and also to a tablet via a separate BT channel. The button at the top of the mouse makes this possible. The mouse has 3 selectable DPI density levels via a button on the bottom. Scrolling is smooth and precise in all settings, but the speed changes accordingly. If I had time, I could get used to it the quickest, but for what I do it's not necessary. The two programmable buttons are located below and behind the thumbpad, which makes them quite awkward to access. There's also a button to toggle the connection, which means sometimes you'll press it rather than the soft key. (You have to hold down to change the connection, so pressing doesn't cause any problems other than you hit the wrong button.) I've replaced the button with one I don't need to access often to help with this. My only other, very minor, issue is that it's difficult to take the mouse to turn it on and off without pressing the buttons on top of the mouse. I started leaving the mouse on all the time. (I use AC Delco alkaline AA batteries.) I changed the batteries last week after 2 months of use. Overall, I'm very happy with the performance and comfort of the mouse and look forward to many years of use.
