Had a logitech before and they make a really good product.

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

Excellent Quality Product

I think this product is a love it or hate it item

Maybe mine was just 0.1% of overall good product but just be aware

Overall I would say it is a great product.

Good product.

Great product for a great price.

I highly recommend this product.

great product, great price

This product, if logitech could just improve the durability and longevity, would be a fantastic mouse

I love their products!

Good product for the price

I have had many of these in the past, it is a good product, but they do wear out (usually the left button)

This is a great product, IF you use a thumb ball mouse.

Good product.

Great Product.

I usually love Logitech products and this is replacing my beloved old wired version whose buttons have finally started giving me trouble

Excellent product

Excellent product.

Product is good but just wasn't for me.

Other than that, good product and light.

Nice product despite being more expensive than similar off-brand products.

Good product and delivery on time

Bought 3 so far, awesome product.

Repeat customer, excellent product.

Great product while it works...

Great product!

This item is a great product because it’s easy when you place your hand on the mouse and you can roll the ball with your thumb.

Otherwise, great product.

great product

Obviously we all like the product or I wouldn't own so many, and indeed it works great

Overall outstanding product and service by Logitech.

this is a fantastic product and blends very well in logitech universe

The mouse from Logitech is in my experience a good product, but it had failed on me about 18 months ago, and the second one I purchased was failing again with the same symptoms.

Great product, can use anywhere

I highly recommend this product to anyone who suffers from arm and hand pain and fatigue.

Solid product with decent range.

I recommend this product to someone who wants to buy a mouse for supporting their wrist.

but I shouldn't have to bother with fixing the product only after 6 months

Great Product

All in all, great product.

Great Product

Excellent product.

I no longer have confidence in Logitech, as this problem has been frequently reported for years, and they continue to put out this faulty product knowing it is going to fail more often than not.

For the last couple years this product has lost all quality

Outstanding product and quality

Great product, great price

Great Product.

A very good product.

Overall, another great product bought on amazon.

Love this product so much bought another one.. works perfectly at home and work.

IT IS NOT A GENUINE LOGITECH product!!!!

Superb product...and very durable!

A fantastic product that I can't live without.

I highly recommend this product.

Less than a year old, and its stops working!It becomes jittery, and no amount of battery changes makes it any betterGo find yourself a better longer lasting product

Amazing product, my coworker ordered it and told me to try it

good product

I think this product is a love it or hate it item

Very nice product

Great product!

I gave it 3 stars because I can't knock the product itself, just the concept, which still has value to people with disabilities.

Do not buy thisIt's really a bad product, very slow and hard to control, it's really

but I got a bad product

I'm finnished with Logitech and all their defective products.

It's a great product for work

Great product.

Excellent product.

I thought I would like the product, but I really can't imagine going back to a typical mouse

Logitech produces great products.

But clearly this product must have design defects or is poorly manufactured.

solid product

Great Product and absolutely fast shipping!

good product

This product is pretty terrible.... mostly because of the distance.. you only have two feet and even then the signal is incredibly bad.. when people come over, they say

This product is awesome, I've others since 2000.

Great product I have 4!

Super product, been using one for several years.

Great Product

Wow great product

great product!

Great product

Just love the product.

For comfort and ergonomic design there is NO better "mouse" product

The wireless receiver that plugs into a USB port on your computer will also connect with other Logitech products, such as their wireless keyboards; super convenient and simple.

Product worked well for about the first week, but then after that it would occasionally lose signal

It is such a wonderfully designed product, too bad Logitech doesn't build things to last

Very good product, easy to use, cheap.

Excellent product for those preferring a trackball

Logitech is a good company with good products i have used for years.
