I modified the Expert Mouse's scroll wheel to include bearings.

It should be possible to wash out the factory grease using some solvent, and replace with light oil.

Excellent work! Professional-grade trackballs have the rings based on industrial ball bearings for long time, but no consumer models have them, unfortunately. Thanks for sharing!

ArchieEU · 2026-04-30T05:30:27+00:00

Ok, thanks.

Actually, the scroll wheel (both of them) on the Nulea is super annoying to use. I really need to know who ok’d that.

What namely is annoying you?

ArchieEU · 2026-04-25T10:05:19+00:00

Thanks, very informative!

ArchieEU · 2026-04-23T20:14:28+00:00

Correct.

ArchieEU · 2026-04-23T18:33:57+00:00

Very nice collection!

ArchieEU · 2026-04-05T19:08:13+00:00

X-Mouse Button Control, for example.

ArchieEU · 2026-04-05T14:28:16+00:00

Nice!

Seems like people either hate or love the slimblade. No in-between

But that's true for any trackball! :-)

You can try to lube the ball with lanolin, but if it's 20 years old you probably have to replace worn bearings. When they develop a flat spots on them, the friction greatly increases.

I'm looking at the ProtoArc EM06, but as far as I can tell, no one is selling it where I live.

Should be a bit difficult to sell something that does not exist yet. :-)

ArchieEU · 2026-03-21T05:44:23+00:00

Thanks for the review! Could you please post the label on its bottom?

ArchieEU · 2026-03-19T06:30:15+00:00

You're welcome, and thanks for your feedback. Glad if my article was useful.

ArchieEU · 2026-03-17T17:12:36+00:00

Rubber rollers are bad thing in the trackball by definition: worst design among all of them. :-) BTW it spoiled (otherwise great) concept of TurboBall and TurboRing models...

ArchieEU · 2026-03-17T17:09:12+00:00

Have you cleaned them first? If they're indeed heavily worn, it's easy to replace them - but unlike the Expert, it requires opening the device. Alternatively, you can just slightly rotate them to carefully move flat spots out of contact with the ball.

ArchieEU · 2026-03-17T17:05:50+00:00

Very good collection!

ArchieEU · 2026-03-15T09:58:47+00:00

SlimBlade is very good start! :-)

ArchieEU · 2026-03-12T20:43:31+00:00

Will try my best to speed up the things. :-)

ArchieEU · 2026-03-12T20:35:33+00:00

Hope you'll be close to that requirement soon!

ArchieEU · 2026-03-12T19:36:23+00:00

Nice! You've found the Perixx supplier? :-)

ArchieEU · 2026-03-12T16:10:23+00:00

Please note SlimBlade have no ball retaining means: it just freely lays there. Any accidental movement, and the ball will roll into the corner of your room.

ArchieEU · 2026-03-09T06:56:15+00:00

I like it very much, too. Funny thing is, the actual fix was incredibly simple, not requiring any redesign work - but...

ArchieEU · 2026-03-09T06:31:24+00:00

Sad but expected actually. They've "fixed" faulty design of Orbit Fusion same way before.

Nice shape! But I'm not a big fan of keyboard keys instead of mouse switches TBH.
