Most customers were happy the trackball was comfortable, easy to use, and worked well with their computer. Some customers were annoyed the trackball only had 2 positions, or the description was wrong.
Summarized ReviewI've been waiting for this device for well over a decade - a Bluetooth version of Logitech's fabled TrackMan Marble Wheel. And this is, indeed, a really nice trackball for use with new laptops that don't have USB
A ports, such as the MacBook/MacBook Pro. Brad J · from AmazonI originally updated from my Logitech M570 because I wanted the extra-fine control this one has as a switch - It was worth it, the heavy base, the 2 position setting etc. The description says "Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degree" which is an outright lie, it is zero or 20, there is no in-between at all. I doubt you would want to set it between and it would just be another thing to break, but it annoys me when product descriptions are just wrong.
Lorry · from AmazonVery comfortable, plastic quality is way better. The top is rubbery, feels much nicer. The bottom is also rubberized, preventing it fron sliding on the desk. It's also pretty heavy, which also helps preventing the sliding.
Murg · from AmazonI purchased the MX Ergo due to shoulder/arm issues that I think stem from using a mouse all day. It took some getting used to, but in general I find the MX Ergo to be very good. I'd only change a few things.
Russ · from AmazonPros +Ergonomic focused design (adjustable angle) +Built-in rechargeable battery+Connects via bluetooth or nano usb transmitter (included) +Can be used and switched between 2 simultaneous computers (pressing a button) +Speed selector (2 positions) +Unlike a traditional mouse, this one does not requires more space to use (only use the thumb)
