very efficient and high quality

Quality of material isn't as great

poor quality

I would give it a 5 star if they used a better quality switch in the buttons, I wear them out.

Logitech has always been a name I trust for good quality products and this trackball (M570

The build quality is good however and the responsiveness is pretty good

This one functions identically, and if it lasts anywhere near as long, Logitech gets my vote, hands down, as the best quality desktop accessory manufacturer in their market.

Excellent Quality Product

Great quality and fast shipping

terrible quality

Great quality and superb for design!

Excellent quality

It’s a nice trackball, decent enough quality for the price

Excellent quality and delivered on schedule

I have found that trackballs that cost more than $40 are a waste of money, because they are very poor quality

The best price and great quality

Low price, good quality

This is my 3rd of these trackball mice and it is clearly a much cheaper build quality than my previous two

This trackball mouse is very easy to use and really good quality

One other thing I want to point out is that the quality of Logitech trackballs wasn't always so bad

Great quality, as expected from Logitech.

but it is too bad that they did not have better quality.

PERFECT SECOND ONE IVE HAD GREAT QUALITY

Overall, it has been my day to day driver for 9 months now and all the buttons work probably, nothing has broken and is overall a great quality mouse to buy

Good quality and should last a very long time with no foreseeable issues.

I have to take away a star because the build quality now is crap

Not great quality....

Good quality

I really had big hopes for this mouse thinking it would be a quality working mouse even paid theextra 1 day fee just to be disappointed the mouse did not do anything i am returning it

Good quality piece overall, but the Back and Forward page buttons do not work!!!

Of course the quality is outstanding since it is from Logitech.

think it’s very good quality.

Outstanding product and quality

For the last couple years this product has lost all quality

So difficult for the first use and soft surfaces, but good quality!

I've found it to be comfortable and of good quality, with quite a few buttons and options for configuration

Probably just a quality issue

Input is accurate and smooth, build quality is great

The quality and performance of the mouse is fine but the concept is a bit baffling.

Great Quality

So difficult for the first use and soft surfaces, but good quality!

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

Even a few months later I still tense weirdly trying to use the mouse like a regular one

so i clean i out regularly
