Update: I popped the little blue thing on the top off with little tabs you can reach through the battery hole. The electrical switch itself is fine, but the thing that holds the wheel has decided not to go down far enough unless I push down and back hard.
I sent a warranty replace request. Given I replaced a near identical mouse with the same problem from the same company, I expect little from the replacement. Fortunately, I can afford a better mouse if needed now thanks to Mastodon!
@Riley of corpse it depends on the brand and how "heavy" your average usage is. Eg. i'm a keyboard crusher, because I learned typing mostly on IBM Model M and similar verrry robust keyboards. Right now I'm smashing my way through the Sharkoon Skiller (Mech) SKG1, which just after about 2 months 9f use starts to show signs of mechanical "wear n tear".
Mice live in a similar kind of .. purgatory. Thus, I've been using gaming mice exclusively for some time /1
@Riley I'm very fond of the Sharkoon Shark Force mice. Got 3 of them so far (Green, Magenta and Black), all still in use.
Also nice: Sharkoon Drakonia, and the Gigabyte GM-6800 (took 4 years to finally break down)
NOT so nice: Logitech G700s. Horrible raw sandpaper surface, esp. for folks being afflichted with RSI. Plus those shoddy frail switches.
@Riley guess I never finished my answer .. but: Most of what Sharkoon produces has been very reliable so far (Sharkoon Sharkforce, Draconia, etc.). Only the mice, not the keyboards (at least the Skiller Mech SKG1 is already starting to fluke out after about 3 months of use).
@Riley .. but that doesn't make it less hard to find really sturdy, reliable input devices that last longer than roughly about a year.
'Nowadays' Logitech devices completely fall flat, thanks to their seemingly very flimsy and mushy produced switches. That of corpse includes the middle mouse button. Just about the only really GOOD thing I'm missing on mice from diff. brands is: The 'free-wheeling' / spinning option from the MX (gaming?) series.
