Unfortunately, after checking Logitech's web site I learned this model only has a 3 year warranty which expired for me less than two months ago.

Alas, my last one died after many good years of service

The most recent failure didn't last a full year, and that was a replacement for another trackball of this kind that failed after two years

First one I bought lasted about a year before it started jittering and just being glitchy

This is the only tech product I've found that's 5 years old and still the best

I'll never go back to a traditional mouse again, I use it everyday for almost a year now and what a great mouse, no issues.

Very disappointed this mouse only last 1.5 years.

Maybe if I replace switches I can get a solid year or more from these things

My first one lasted 2 years until the primary (left button) microswitch failed

i dont use normal mice any more.yes, the microcontroller that manages the left click may die over time, but ive had 3 of these, and the oldest one lasted over 3 years before i had any issues with double clicking.

My ancient, corded, Logitech Trackman with the red ball, same basic design as this one, finally failed - aftar 15+ years!

The first one I had for almost 5 years, but the next two only lasted about 2 years before they were unusable

Prob is they only last 1-2 years before failing which is why only 4 stars

when you do you'll be wondering what you were doing with a traditional mouse all these years!

Thankfully they lowered the price so the fact you'll be lucky if it lasts the year isn't as bad

Good Mouse seems like it does what it's supposed to do but about 2 or 3 years it's gone

I had to retrain my brain and fingers, which wasn't too difficult, and so far I've gotten another year's worth of service out of it.

Works exactly as I expected

After using the ball for a month or so, it becomes apparent it's made of paper mache or some inferior material as it hangs on the points it's supposed to roll around on

But after a few years either plan on replacing it or soldering in new switches as they tend to fail and you

Never thought I would like a

Works as it should.

Even with fresh batteries it would be jumpy and glitch as if the laser mechanism could not see the ball was moving

so i decided to try something new, and i got a mechanical keyboard which i liked a
