The exclusion of such basic trackball features (dongle storage, easy ball removal, etc.) make the MX Ergo less than ideal if you plan on using it for travel. Compound this issue with the fact that the hole to remove the ball is now too small to fit a finger in – meaning you will need to pop the ball out with a pencil to clean it – and the bottom of the Logitech MX Ergo really has me scratching my head.

Because of the rechargeable battery, there is a micro USB port featured on the front of the device, which is positioned well enough that you can charge during use without the cable getting in your way. Personally, I prefer to have the 2 AA battery approach, but the battery life for the MX Ergo is long enough (5+ months) that I don’t mind the rechargeable battery too much.
#LOGITECH TRACKMAN FX UPGRADE#
In an attempt to upgrade the design of the Logitech M570, the MX Ergo features an inbuilt rechargeable battery that cannot be accessed by the bottom of the device. Something like this Perrix replacement ball has been reported to work well, although it is recommended to only use the glossy finish balls as the matte finish seem to have dragging issues. It is highly recommended to replace the stock ball if you plan on using this mouse long term. This does not appear to be related to the bearings, as the M570 ball immediately felt smooth as butter and performed exceptionally well without the need for any break-in period at all. I gave the MX Ergo a couple of weeks to break-in, but regrettably the break-in never happened. The stock gray ball that ships with the device is one of the scratchiest balls I’ve used in a trackball mouse, and had to be replaced with the ball from the M570. Unfortunately, the ball of the Logitech MX Ergo completely missed the mark when it comes to build quality. In addition to the upgraded materials, the outer shell is also wider across the palm, making for a much more comfortable experience when using the trackball for an extended period of time. To add to the premium feel, the MX Ergo also features a solid metal plate on the bottom of the device, which allows for the mouse to be tilted at a 20 degree angle for better ergonomics. Featuring a hard plastic shell with a spongey/grippy layer of material on the upper housing, the MX Ergo feels like it’s built to last for a long time. In contrast to it’s predecessor (the Logitech M570), the MX Ergo has a very premium feel to it. The button layout is standard and should feel extremely familiar if you have used the aforementioned Logitech M570 trackball mouse. Internally, the MX Ergo has forgone the standard 2 AA batteries approach seen in the M570, instead opting for a built-in rechargeable battery.
#LOGITECH TRACKMAN FX BLUETOOTH#
The frills are lacking with this particular trackball, offering only Bluetooth and wireless dongle connectivity and a DPI button with 2 settings. Aside from the tilt, the MX Ergo also features a wider layout which adds additional space for the pinky to rest comfortably instead of hanging over the edge of the trackball.

Despite my initial concerns, the tilt is much more than just a marketing ploy, and proves to be a fantastic addition to the mouse. One of the biggest features of the Logitech MX Ergo is the variable tilt, which allows you to use the trackball in either a flat position, or inclined 20 degrees. Although the MX Ergo doesn’t have all of the frills of other trackballs (see Elecom Huge), if you’re looking for a solid, well-constructed device that can get the job done comfortably, the Logitech MX Ergo might just be the trackball for you. The curve and overall design of the MX Ergo body is a major improvement over the venerable Logitech M570, and the added tilt functionality is a much welcome addition.

While it’s primarily known as a gateway into the trackball world, the Logitech MX Ergo serves as the final resting place for many trackball enthusiasts as well. Given the relatively standard design, the MX Ergo appeals to a much larger audience than something like the Logitech Trackman Marble, and allows for all of the benefits of a trackball without overcomplicating the experience. While it may not offer the largest feature set or a revolutionary design, one thing is for certain – it is one of the easiest devices to transition from a regular mouse to a trackball. The Logitech MX Ergo consistently ranks as one of the highest rated trackballs on many review sites and forums.
