Review on 🖱️ Upgrade DEFT Wired Finger-Operated Trackball Mouse by ELECOM - 8-Button Function with Smooth Tracking, Optical Gaming Sensor, Ergonomic Design - Compatible with Windows / Mac - Red Ball (M-DT2URBK-G) by Donotello Figueroa

I really liked this product. I really wanted to love it. I really had to love it. But unfortunately not usable. I've been using Microsoft Trackball Explorer for 15 years and it's on its last legs. Unfortunately, it was discontinued almost ten years ago. I was looking for a new middle/index finger trackball with a scroll wheel and 5 or more easily accessible and customizable buttons for my CAD program. The more buttons the better. It seemed like the perfect solution. Except that it isn't. Here are the problems: The trackball is too small. I have medium sized hands and my hand cramps after a few hours of use. The ball itself is too small and cannot be precisely controlled. The left-most button, which is left-clicked by default, is almost impossible to use. It can only be activated by fully depressing its front end. But if you put your hand that far forward, the wheel and ball are too far back to use. The wheel knob is too tight to use. The incline buttons on the wheel are also too narrow. The left incline button (down) can be used when operating the wheel with the tip of your thumb, but the right incline button (up) cannot be pressed. The right button is extremely impractical. The slim button that protrudes from the case is too high to be pressed with a finger resting on the case and too narrow to rest a finger on, not that it would be comfortable in such an awkward position. A setup similar to a thumb-actuated trackball (buttons flush with the body) would be significantly better and would offer an extra button. The only way to use this trackball is to place your hand on the trackball with your palm on the table and your fingertips on the ball. For this to work, you must assign the left click function to the left back button (above and behind the tilt wheel) and discard the default left click button, left forward button, steering wheel button, and trackwheel tilt button. But then you're left with a 5-button trackball with a very awkward right-click and a ball too small for precise control. That's why we got two stars. I believe this product has great potential. By making the body a little bigger, moving a few things, using less rigid switches, and using a bigger ball, they can succeed!
