There's the trackball, left button, mini left button (previous page), right button and mini right button (next page). And that's it, no scroll available.
It's only possible to scroll manually by pressing the left button + trackball. Bit of a shame, but great quality!
Might be worth seeing about some macro commands or gesture commands as a third party program. You could even map an enable to something stupid like scroll lock on the keyboard.
okay boomer
wireless isnt as unreliable as you make it out to be, for interference you would have to be doing something major to cause that.
propriety dongles really dont matter you are paying for a good product of course it would be propriety if everyone used the same dongle i would imagine the interference then would be the same.
latency isnt an issue and its been shown that some wireless mice actually have less latency than cabled.
batteries pff most things last forever or are rechargeable in a fraction of the use time, hell most will work wired while charging.
also what configuration issues, what system are you using where a wireless is hard to config, everything has its own drivers/software regardless or wired or wireless and either way you would config it.
Random laptop bluetooth has less latency than my glorious ps/2? Also I would like to see that test -- I am betting on it being some super slick one gamed for it vs a USB 1.1 ancient thing that might have had a sister model in the range with a ball in it.
Config issues. I take the lead, I plug it in, job is jobbed unless I need to do something completely custom. I am sorry if you bought into the lies that said you need always on DRM to use your mouse.
Batteries are an issue. They last forever? Have you never had a laptop, phone, power tool or similar have its battery crap out on you? You stand a chance of finding a replacement one of those at least as well (or at least finding it is an 18650 you can solder a replacement in for) but whatever proprietary flat pack nonsense the fly by night peripherals manufacturers use I hold no hope of finding. Maybe I would be lucky and there is one of the same chemistry and the battery is self managed but I would first have to check that.
Proprietary dongles are an instant no buy for me unless it is some very expensive software with a professional purpose, and you know I will be looking for a crack before the download is even finished. They have caused that much hassle over the years that it is known standards or go home. Not to mention if I am down a USB port anyway...
Interference. It is better than it was but still eminently achievable and not even just by trying to run 30 different things at once on similar frequencies.
All this to not have a wire that already reaches most places (my wired mouse has metres of braided cable, and my headphones even more) and if not a 20p extension most of us have a dozen of will finish the job.
