I personally use Logitech's G403 wireless and I love it (the middle mouse button is just that, a button)...though mice are highly subjective as we all have different needs, hand sizes, etc.

That being said, I would make sure that whatever mouse you choose works with piper if you want an easy to use GUI for configuring your mouse. Note that some mouse vendors have their own open source config tools but piper is pretty vendor agnostic.

Hi! I'm sorry I can't really recommend a good mouse to you, but in case your dying mouse refers to the infamous problem that plagues Logitech mice where clicks start behaving randomly, usually with unsolicited double-clicks, I'd suggest trying to fix it before changing it. :) It's relatively easy not so hard. The culprit is a very tiny piece of metal inside the microswitch that acts as a spring. You can either bend it into shape or change it, which is very cheap. Here is a very detailed article on that :

I'm not sure it applies to your specific model, but it might be worth a look.

And if your mouse is dying for other reasons, well at least I shared a very useful link that might help many. (And I think it was worth creating an account to do just that. ^^' )

G403 doesn't look too bad actually. The Chinese one is silly price. Almost worth to order it just as a spare. :D

@Sigbjorn Buttons are still fine actually. It's just general wear, especially the sliding surfaces, and probably an almost break in the cable somewhere.

My mouse is Logitech M705, I have been using it for 5 or 6 years. It's wireless and laser. It doesn't switch off when you don't use it for a minute, so you don't have to click it first to use it, unlike optical wireless mice. But two AA batteries can power it for more than two years! The downside is that, as every Logitech mouse, after a couple years its left button starts double-clicking, as described above.

I could never find a proper replacement for my mx518... But on newegg, a few weeks ago, I found someone selling 'new' in bulk packaging mx518s. So I bought one, and it is just as good as the original. Best mouse ever.

For me I use corsair mouse , especially M65 Pro RGB :)

Actually went to a store to feel a few mice IRL. None of the Logitech's unfortunately. One felt instantly right, the "Razer Mamba Tournament Edition 5G". But that's a pricey beast and I wonder if the quality is actually good enough to warrant that price tag.

I'm using Logitech G400s, since I like its ergonomics.
