Excerpt: I've purchased a number of these (wireless and wired versions) in the past and found them to be the best way to navigate around a screen. Additionally, it provides a significant amount of relief related to carpal tunnel syndrome.
Pros: Comfortable Design, Fast Response, Great Features, Great Wrist Strain Relief
Excerpt: After having issues with my wrist, I switched to this trackball and it is much more comfortable. Customizable buttons helps a lot too when you assign them to minimize, close etc. Also great battery life which is more than a year for me.
Pros: Accurate Tracking, Comfortable Design, Customizable buttons, Fast Response, Works On Any Surface
Summary: Battery life is outstanding, over a year with heavy use. And there is a battery monitor that will tell you how many days or how much % is left in the battery. You can also customize the speed and accuracy of your pointer, and set gaming specs.
Pros: For the last 15 years, I keep asking (to anyone who will listen) why they would use a mouse that you have to pick up and move around, when with (this) trackball you only move your thumb. IT'S A NO BRAINER! OK, it might take you a few days to get used to it, but it is all around faster for gaming ...
Cons: No so much a con, but mine seem to wear out about every 4 years, with heavy gaming and heavy common use, but these used to be around $65!
Summary: It's a shame there aren't more options to choose from where thumb-operated trackballs are concerned. They're my favorite type of input device and the best I can do is buy old used Microsoft Optical Trackballs, which tend to last and last for me. Logitech has no competition in this area.
Pros: Great design, great concept, wireless is nice
Cons: poor construction. I've owned about 5 of these either purchased new or replaced under warranty. Each one has inevitably failed to operate properly in under 12 months or so (yes, before the first set of batteries even starts dying out). I always get the infamous double click issue where a single c...

Summary: I buy these since I have limited range in my right hand and wrist. These make it simple to do standard thigns with the computer while not leaving the wrist area sore after prolonged use. Highly recommend this mouse for those in similar condition or suffer from carpul tunnel syndrom
Pros: Works great for someone with limited desktop space. Perfect for keeping hand and wrist in ergonomic position limiting the wear and tear on tendons.
Pros: If you're looking for a thumb trackball peripheral, look no further. I absolutely love these and the AA battery lasts at least six months on gaming use. Not bad for a wireless.
Cons: I will have gone through two of these within a 5 year period. The first one lasted about 3 years before the rollers gave out and this current one double clicks periodically on left click. Because of gaming I can't have this happen, so I'm about to order another one.
Summary: I almost never have problems with Logitech devices in general.
Pros: This is my personal favorite mouse-device. It has withstood gaming for a stretch of about 5 years. Just plugs in and works. If it becomes stuttery and twitchy it needs cleaning, which is accomplished by a few fingernail flicks. The configuration fits my hand well and requires minimal desk real es...
Cons: None. Unless you count the other people and floors issue.
