As others have said, Logitech MX Ergo springs to mind. Lacks bearings and repairability, but is of decent quality.

If Logitech isn't your thing, there's also the ProtoArc EM01 - basically an MX Ergo clone with RGB and USB-C, but inferior tilt.

There're also Elecom, whose EX-G is also decent but on a personal level, Im not a fan of the right click - too light. Sanwa -- Amazon Link -- and Perixx are competitors to/similar to the Elecom offerings.

Ploopy might be your best bet in terms of repairability, though their offering is a little rough around the edges (figuratively and literally, they're a 3d-printed startup but seem to have a decent following).

Links with the exception of Sanwa are to the manufacturer's pages.

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.

I love my mx570 but it is rf not bluetooth. The MX ergo is nice too, but that's internal not aa batteries.

When you clean it, are you just cleaning the ball? Depending on the type of trackball, there may be some small plastic rollers inside that have gunk built up on them. If you can safely take it apart and clean those well, it can make a world of difference. Back in the days of mechanical mice, this was a pretty common issue.

If your trackball uses some kind of optical sensor(s) and isn't mechanical, my apologies for wasting your time.

My partner uses a Logitech MX Ergo. It doesn't match all your specs, but it's a very nice mouse. The initially purchased mouse was refurbished from Amazon and it was having problems connecting to multiple devices. Logitech sent a completely new mouse no questions asked!

Every now and then my MX ergo would feel like that, I take it apart and place the plastic ball holder (just the actual plastic part, removing all electronics) in hot soapy water for a few minutes. It has 3 little ceramic bearings that even with regular cleanup end up gunking up. While wet, i use the ball to jog the bearings around, then rinse with isopropyl and let it dry. Feels as good as new.

Is the current trackball removable from the current one?

I wonder if you can replace that component with something new as long as it still fits, can register the movement.

That is if you really like your current one and want to find a way to “refresh” it

I've not seen one that meets all of those. Best one I've ever used is the Logictech MX Ergo

• Wireless with multi-device support
• Internal rechargeable battery
• Plastic roller style bearings
• Tiltable
• Not repairable, and the mouse button click sensors fail at a fairly high rate. I blow threw one of these about once every 18-24 months. I know you can repair this, but I'm not willing to dust off my soldering skills after decades of disuse.
