A datasheet (PDF) for the device claims that the Mobi Fold is “built to withstand 50,000 folds and unfolds.” Logitech said it tested it “under controlled conditions until malfunctions or functional issues occur.”

The Mobi Fold seems to have a good handle on portability, including ease of use and battery life. But the mouse’s tented shape doesn’t look particularly comfortable, especially for long-term use.
When folded, the mouse forms an approximately 90-degree angle at which your palm must rest. I find the most comfortable mice to be ones that fill the circular opening of my palm, and the Moby Fold doesn’t fit that. Similar-sized mice, such as the Dell MS700 and Microsoft Surface Arc Mouse, are a bit more forgiving here, offering a more rounded, arched shape when in use.

The angle of the Mobi Fold is more acute.

The Mobi Fold’s buttons aren’t as tactile as other mice. The left and right-click buttons are flat, and Logitech has replaced the scroll wheel with a touch panel. Below the touch panel are two clear travel buttons that can be programmed with the Logi Option+ software. But since the mouse does not have onboard memory, the device will not remember programmed inputs unless you program the mouse with Option+ on the paired computer. Logitech devices have become more software-dependent this way, which is a shame considering how easy many of the company’s wireless devices are to use with multiple systems.
my favorite travel mouse
When it comes to travel mice, my years-long favorite has been Logitech’s MX Anywhere 3 (or the newer, quieter Anywhere 3S). It weighs more than the Moby Fold (3.49 ounces vs. 2.79 ounces) and takes up more space (13.69-cubic-inches when folded compared to the Moby Fold’s 4.83-cubic-inches). But the rounded hump and more advanced and tactile scroll wheel are worth the extra girth.
Today’s announcement from Logitech claimed that the Mobi Fold “reduces muscle strain by up to 22 percent compared to a laptop trackpad,” but I doubt the MX Anywhere 3 can reduce strain further. And its button layout brings familiarity and efficiency.

The battery on the MX Anywhere 3 should also last longer. Logitech claims that the Bluetooth mouse can last up to 70 days without a charge, while the Mobi Fold can last up to 30 days. However, the Mobi Fold has an exemplary advantage in its replaceable, rechargeable battery.
The Mobi Fold is more portable, but the MX Anywhere 3 is still quite small. When it comes to mouse comfort and usefulness, sometimes more is more than that.
