I bought the Steelseries Aerox 3 and am very happy with it. It works with both bluetooth and wireless usb-c The bluetooth connection actually works quite well, and I use that the majority of the time for computer work and light gaming. Much better than some of my previous experiences with bluetooth mice a few years back. I only have to use the usb-c receiver when i’m playing something that requires alot of precision.
Yeah, it’s a great mouse, isn’t it? The tracking is incredible and the wireless works great. I use it for like six hours a day and love it.
Wish the dongle was smaller though.
Agree that it’s a super mouse but the single is too large.
Quick update in case anyone’s still interested…
I ended up getting the smaller ambidextrous Matias mouse (the non-Pro version). Its dongle is ridiculously tiny:
It’s so tiny that the mouse even comes with a USB-C puller tab for getting the dongle out of tighter areas. Good thing, too, or it would’ve been stuck in my USB hub forever. It can definitely live permanently attached to a laptop and not risk breaking off. It’s awesome miniaturization on Matias’s part, and I hope they will consider licensing it out to other USB-C mice manufacturers (like Steelseries, whose dongle is a leviathan in comparison.)
The Matias mouse is quite well-built and designed, especially for a lesser-known Canadian company. The box says it’ll last up to a year on a single AA battery. It is not as precise as the Aerox 3, but it should be fine for everyday office work. I wouldn’t use it for gaming.
Sadly, it doesn’t quite fit my hand as well as I hoped it would. I don’t really want to return it because the company made a great product, but I’m not going to end up using it very much.
If any Doper is still on the lookout for a wireless USB-C mouse, I’d be happy to send the Matias to you for the price of postage. PM me.
Those of you who bought an Aerox 3, like @puzzlegal and @Quintas … anyone having issues with the scroll wheel yet?
I’ve had mine for less than a year, but the scroll wheel kept getting worse and worse. If I scroll down too quickly, about 1 out of every 10 scroll notches would cause it to scroll up instead, which would cause the page to jitter up and down. At first I thought it was just a fluke — maybe my finger was placed weird or something — but the problem increased in frequency, and over the last few weeks it’s gotten noticeably worse and I can’t really use the scrollwheel anymore 
This is the second SteelSeries mouse I’ve had with the same problem… I didn’t realize it was a pattern until now.
There are a bunch of people with similar problems on reddit, like:

And one who managed to fix it only by taking the mouse apart and replacing the “scroll encoder” with a better replacement part: Fixing Aerox 9 Scroll Jumping : steelseries
Sad. I asked SteelSeries about it, and at first they insisted it was a firmware problem and I had to jump through a few hoops to prove that it isn’t. They finally offered me an RMA replacement for the same mouse, but they require you to first destroy the existing one (rip it apart, breaking the buttons and taking a picture of the remains) before they’ll ship you a replacement, meaning you’ll be mouseless for several days. They don’t offer a repair service, only RMA replacements, and only if you first physically destroy your existing mouse.
Sadly, this left a pretty bad impression of their build quality and support overall… It was an otherwise terrific mouse, but it seems like the scrolling issue is probably an inevitability, either a design defect or maybe a poor-quality scroll encoder component. Too bad.
Just providing this warning for anyone else who might’ve purchased one… watch out for any signs of scroll issues, let the company know ASAP, but have a backup mouse just in case.
I have not. But I’m mostly using the Matias mouse, due to its tiny dongle. So if it’s a wear & tear issue, i might just not have encountered it, yet.
