Customer Ratings & Reviews

It looks huge, compared to other mouses. But once you use it, you would fall in love with this, it snugs perfectly in your palm.

Have used these Logitech Marble trackballs for years. This is my third in fact. I use it for CAD, Photoshop, and all around pointing.

My old track-ball mouse died, mostly because the connecting wire (USB) was bent too often. This new one felt very awkward at first, because it worked differently than the old one. However, with time, I have gotten used to the new way, and am satisfied with it. Sometimes I wish it would work same as the old one, but then I remember bending the wire to get it into comfortable position - new one does not have any wires (UV operations) so it cannot die the same way. OK!

If you've never used a trackball mouse before, there's a little bit of a learning curve. Once you're used to it, it's a great experience as it cuts down on all the dragging you used to do. Appreciate Logitech's new feature allowing you to connect multiple devices to one USB dongle.

I bought this to replace my old Logitech trackball mouse. I love the fact that this one is wireless. Took a bit of getting used to as it is configured differently than my old one, but after about a day it's all good. Works really well. Glad I made this purchase.

My husband uses this mouse, it is his third one and they are getting harder to find. He is bedridden and can not use a mouse pad.

I'm hooked on roller balls for preventing wrist injuries. I've been using a corded one for years and when I got a laptop I was very happy to find a wireless one for travel. It works just fine. However, there is a little piece that has to be plugged into a port so I needed an adapter to accommodate that. Still very worthwhile.

I like this much more than an mouse. I have one on all of you computers. I used to have wrist problems and this seemed to fix it.

I have had the hardest time finding a trackball that worked as precisely as I need. I wanted something with a little more detail than my mouse and this trackball worked perfectly. The fact that it's cordless makes it even better and the battery life is pretty good. I would recommend.

first off I had a lot of fear buying this product. I hate anything with a battery in it. I had been using an older corded trackball the last 15 years, the same one as this except its wireless now. It works great, battery life not so good, but I do tons of clicks each day so yes I eat up the battery. It is very nice and well its made by logitech.

This has been my mouse of choice for several computers. When I move out a computer I give the mouse with it so I can get a new one.

I use this mouse at home, work, and on the road because in my opinion it’s the finest product on the market today. Ease of use and ease to adjust to your liking makes for a pleasant experience at all times. Don’t hold back!

This Logitech mouse has very good functional capabilities for the price. This object has very good form factor.

This mouse is wonderful for working while sitting in my lounge chair. I can work without having to move my arm.

I HAVE USED LOGITECH TRACKBALLS FOR YEARS. THIS ONE IS THE BEST BY FAR. DOES USE MUCH BATTERY. WHAT ESLE CAN I SAY. IT'S GREAT!!

I purchased this mouse because more often than not I'm not really wanting to work so hard for my mouse to move across the screen. This is specifically true when I'm working on photos and other digital media projects. This mouse allows me to keep a relaxed hand and better control the cursor. Added bonus is that it's wireless!

I'm not a gamer, and this mouse probably would not do well as a gaming mouse, but as an easy to use portable mouse this is great. Using your thumb to navigate a computer screen is easy and accurate. Once you get used to this mouse you'll never want to go back. I use one at home and at the office.

I was looking for an upgraded mouse for my iMac. I'm not a big fan of the apple mouse due to it's limited functionality. I have owned a trackball mouse before and always enjoyed using it. Probably not the best use for gaming, but it is definitely an upgrade for my iMac and works flawlessly. I would definitely recommend.

Love it. Since I use this at least 8-9 hours a day Ive had to replace the batteries within 3 weeks but otherwise no issues at all.

I've used these for several years and they are the only mouse I buy. If I'm placed in a different lab I take this mouse and attach it to the computer. I do graphics and it's the best for the job, I don't have to move the mouse around. I use both wireless and wired.
