Digi Base [Made in Japan: 25-degree fixed angle] This is a 25° tilt stand for the Logicool (Logitech) MX ERGO and MX ERGO S. Includes 2 non-slip stickers. *Trackball body not included. [Compatible models] MX ERGO (MXTB1d, MXTB1s), MX ERGO S (MXTB2d, MXTB2) You can use it with a further angle (25°) than the standard tilt angle of 20°. Adjusting to an angle that suits your hand reduces the strain on your wrist. Instead of the metal plate, attach this tilt stand to the mouse body. It is fixed to the mouse side magnet with built-in steel and will not fall off. (Cannot be used with the metal plate at the same time.) Weighing a mere 23g, it is much lighter than the metal plate (approx. 97g). It is very comfortable to carry around. Two non-slip stickers are included. You can apply them to the bottom of the stand in any position you like. There may be streaks and fuzz on the surface that occur during the manufacturing process, but they do not affect use. Thank you for viewing.
