My current trackball has lost its smoothness and feels “sticky” no matter how well, or often I clean it.
So, I’m looking for a trackball (thumb controlled) with the following features:
- Bluetooth wireless with support for at least two connections (for laptop and PC media station).
- Uses AA or AAA batteries.
- Uses bearings.
- Set at a tilt/ergo angle.
- Repairability is also important, but not a total dealbreaker if the mouse is high-enough quality.
So far, most that I’ve found will lack one of those features, but I’d really like to have all of them, if possible.
UPDATE: Thanks to everyone who offered tips on getting my current trackball working better. Today, trying to roll the ball left became very difficult, like it didn’t want to move. I took it out, looked at the little white ball (bearing?) supports that the ball should be rolling on, and noticed that the left-most one was almost pushed in, and flush with the cup that the ball sits in. The other two are higher up, so the ball can “float” on those, but not this other one. The manufacturer is already sending a replacement mouse, so it should work better, but I’d still like to find my unicorn 😄
You may try to find where your ball stick/grind in the cup, and fix it.
This is what I did with my Sanwa Gravi, I liked the design so much, index ball, thumb LMB/RMB with wheel in the middle, that when it ground in the cup, I basically took my dremel tool with a kind of sanding ball attached and ground the places where it was touching. I also changed the bearing (like in this post), and also put a LCOT ball (biggest improvement, as it is maybe 0.5-1mm larger so it really stands on the bearings and not in the cup. Some people changes the switches too, but I like them because they are completely quiet and I never had any problem with them (compared to logitech switches in the M570…)
Using it for 1.5 year now and it’s fabulous.
It supports a USB dongle and 2 bluetooth connections, and is using 2x AAA batteries.
I love it so much that when I bought it, I bought another one as a backup, that I fully moded too, in case of the 1st one die one day.
