Isn't too much buttons? Looks difficult to use with 20 buttons! ^_^

Usually the M100s I used to buy died within 12 months. It's possible I have a harder grip than you do, so I put much more force into my clicks. In the end I found them too awkward to hold and needed a more ergonomic grip... and I enjoy mice with variable DPI settings. I also like a slightly heavier mouse so my movements are smoother and overshoot a bit less.

But if you've had a M100 that's lasted more than a year without falling apart or having the micoswitches go bad I'd say you're lucky.

EDIT: I've also had a M105's LED fail. The sensor still worked, but not the light. So it's not all about the microswitches ... the mice are cheap for a reason.

The whole space argument is a bit silly. I have my mouse set on high sensitivity because I don't feel like dragging it all over creation - all it needs is a slight arm/hand movement - and the max space I actually need for movement is maybe 7 by 7 inches (hell, I don't even use over half of my mousepad).

As for ergonomics, that may be true, but trackballs tend to suffer highly in accuracy in comparison. I've used mainly trackballs for 8-9 years a while back, and I could never ever get the smooth movement or accuracy that I get from using even the most basic mouse. So after my last trackball died I just decided not to bother anymore. *shrug*

It really depends on what you play, what kind of ergonomic and features you need.

Personally after having researched mice for months, and wanting to mostly play FPS games, I've settled for the Orochi v2. The small size is great for finger tip and claw grip, it's wireless which is great as I don't like cods, and its supports both bluetooth and 2.4GHz which is great for my setup where I need to switch between laptop and PC. That said, if I played more MMORPGs or had very large hands, then it's not a great mouse due to limited (standard) number of buttons and small size.

I recommend checking out https://www.rocketjumpninja.com and his Youtube channel. It is more FPS focussed though, however the principles behind mouse shape, size, and fit for your hand still apply regardless of genre.

Lastly, don't skimp on a good mouse pad. It also makes a huge difference as well. Personally I use the Endgame Gear MPC Codura pads as they're very low friction, static, and very durable. I recommend checking out https://www.youtube.com/c/boardzy who does great reviews on mice and mousepads.

I just use a good old Intellimouse - or a Microsoft Comfort Mouse, depending on which machine I'm using. They're comfortable, have enough buttons (L,R,Clickable wheel, Forward and Back buttons on the side) and in all honesty, I've never seen a need to use anything else.

still going strong after over 10 years

Your misapprehension of my point is due, in part, to my incorrect phrasing in the above (highlighted) clause. I require a pointing device that is stationary.

:)

Thanks for the input. That would certainly explain a lot.

Honestly, I don't exert a significant portion of my strength when clicking the mouse on a regular basis (maybe the occasional bout of frustration, but it is very uncommon and even then, I don't click with all my strength), though if I did, I (and probably most adults I would gather) might need much sturdier equipment (I certainly haven't troubleshooted my computer mice in this way).

For the awkwardness to hold, I guess that's a personal factor. The mouse is certainly a lot smaller than my hand so I only use the upper left part of my hand (my index and my middle finger are resting on both buttons, my thumb is on the left of the mouse and my two other digits are on the right, the mouse occupies ~50% of my palm's width and maybe ~33% of its height). Most of the hand is not engaged, but I'm kind of used to it. Maybe if it was a completely new experience, I'd want something to occupies my entire hand, I'm not sure. I don't think of it much honestly, it is very reflexive at this point.

Man i wonder why i just don't have luck with mouses.
The current some trust mouse wireless is double left clicking and the middle wheel isn't corretly registering sometimes when i roll it down it also likes to go up or or when i roll it up it also likes to go down.
And the logitech g203 gaming prodigy mouse that is wired also didn't last long enough and is double clicking the left click

I have a Zowie S2.

Uhh! That one looks good! I have OCD so I can't use every mouse but this might be suitable for me :)

I'm usually not a big fan of Microsoft (I've been a Linux-only user for years), but I found out Microsoft mice are the best. Very durable. I wouldn't buy anything else.

You're welcome, but I'm not sure if they're still selling it, sadly.
There's a new version M650L, but I haven't tried it. Also there's no border to rest the fingers anymore.

I own the standard 'signature' version of it (only bought it a week or so ago) and love it. Though I still currently own a lot of Logitech mice, so I may be a little bias...
