I've been using the MC Saite Trackball for a while now, and I wanted to share some first impressions.

Overall, I'm actually enjoying it more than I expected.

I can remap all of the buttons using SteerMouse on macOS, which makes it much more flexible.

Since it uses a 55 mm ball, anyone who has used a Kensington SlimBlade should feel comfortable almost immediately. The ball movement feels very familiar.

The button layout is also similar to the SlimBlade, with four main buttons. In fact, I think the button placement is even better because they're positioned where they're easier to click. Personally, I find it more comfortable than the SlimBlade.

Things I wish were different

My biggest complaint is the scroll wheel placement.

I really wish the scroll wheel were located above the ball instead of below it. Every time I want to scroll, I have to move my hand away from the ball, which interrupts the workflow.

To work around this, I'm using SteerMouse Chords to enable a scrolling mode, so I rarely need to touch the physical scroll wheel anymore.

Another downside is the switch noise. The click sound is quite loud, similar to the SlimBlade. It's not a big issue at home, but it's definitely noticeable in a quiet office.

Modding plans

I'm thinking about modifying the trackball.

My first idea is to:

• Replace the switches with silent switches
• Replace the stock bearings with silicon nitride (Si₃N₄) ceramic bearings

I'm also considering something a bit more ambitious.

I'd like to disassemble it and see if it's possible to rotate the sensor board by 90 degrees.

If that works, I could physically rotate the entire trackball by 90 degrees so that the scroll wheel ends up on the right side instead of the bottom.

I think that layout would be much more ergonomic for me.

Since I already remap all of the buttons with SteerMouse, changing the physical orientation wouldn't be a problem.

I've included a link below that shows the teardown photos and internal structure, in case anyone is interested or has experience with this kind of modification.

Any thoughts or suggestions would be greatly appreciated!
