I tried using ELECOM's trackball mouse 'M-IT11DRBK', which allows you to hold the mouse in a comfortable position and has a bearing that allows the ball to roll smoothly.
ELECOM has been selling the wireless trackball mouse ' M-IT11DRBK ' since March 2024. The ergonomic design allows you to operate it in a comfortable position, and the ball is supported by bearings, giving you the feeling of floating in the air. I had the opportunity to try out the M-IT11DRBK, so I checked out its appearance and usability.
2.4GHz Wireless Trackball 'IST' 5 Button Bearing Model - M-IT11DRBK
The outer box of the M-IT11DRBK looks like this. There are two main body colors, 'black' and 'white', and the one I'm reviewing this time is black.
Inside the box were the M-IT11DRBK unit and a removal tool.
This is what the M-IT11DRBK looks like from above. The dimensions are 96mm wide x 126mm deep x 52mm high.
In the center are the mouse wheel, left and right click buttons, the power switch, the 'forward' button, and the 'back' button. Each button except the power switch
There is a trackball on the left side.
The bottom contains the battery cover, a hole for removing the trackball, and a USB receiver for connecting to a PC.
This is what it looks like when you open the battery cover. The M-IT11DRBK runs on one AA battery, but it comes with one included, so you don't need to buy one separately.
You can remove the trackball by pressing it with a pen or something similar through the hole on the bottom.
By removing the trackball, you can see the sensors, bearings, etc. installed.
The bearings can be removed using the included removal tool, and can also be replaced with
The actual weight including the battery and USB receiver is 141g.
To connect the M-IT11DRBK to your PC, insert the included USB receiver into a USB port on your PC.
Turn on the power switch on the top and the connection is complete.
This is what the M-IT11DRBK looks like when you hold it. Unlike a typical mouse, the M-IT11DRBK is a trackball mouse, and you control the cursor by moving the ball. Therefore, your thumb naturally touches the ball.
Below is a video of the M-IT11DRBK clicking and rolling ball sounds. Each click makes a relatively loud 'click' sound, so caution is required in quiet places such as cafes and libraries. However, unlike a typical mouse, there is no need to move the mouse itself to operate the cursor, so there is no sound of the mouse hitting the desk when moved.
