Summary: This mouse performs as flawlessly as a full size optical mouse. I would consider a few benefits to owning this mouse as I have: smaller to transport, shorter wire that doesn't get in the way in cramped travel locations, no batteries to replace or to rattle around as some wireless mouse brands do. I am very pleased with its performance.
Summary: The thing that I like about this mouse is that the buttons are easy to click, very little pressure needed. The is really helping with the pain in my arm/wrist. It is likely that you will need a USB extension cable if using this on a docking station or desktop computer. It would be even better if they could toenail in a side button for browser back functionality.
Summary: This mouse is way too small (and I have small hands, so I can imagine what a pain it is for someone with larger hands), so part of your hand is always kind of raised up, creating strain on the hand and up into the arm (when used for a longer period of time). I've been using it on a desk and I've needed to get a mouse pad for traction because the mouse cursor doesn't stay in one place, making the cursor move all over the page/screen. Better off getting another mouse.
Summary: Purchased this mouse for my laptop. Flows nice and smooth over mouse pad. It is a mini mouse, so it is very comfortable, surface has a nice feel to it. My son is left handed and he uses it with ease. Nothing to set up, just plug into USB port and you're ready to go.
Summary: Stumbled on this mouse by sheer accident many years ago. I am a gamer, and find this an awesome mouse, and repeatedly buy them over and over when replacement is needed (due to heavy use of scroll wheel from gaming). * They aren't big! I love for gaming, application development/programming, surfing, everything. Due to its small size and simplicity (not too many buttons), you can rip it back and forth quickly, and get better reaction performance in any game.
Summary: I have had this mouse for years now, and it has seen constant use. Let me just say that it works like a charm. It's cute, it lights up bright, and, well... it just works. The only problem I've had with mine is that now, after years of use with no problems, the scroller wheel is getting stuck sometimes. I think it may have something stuck in it, so I recommend not eating at your desk (something I have the bad habit of doing).
Summary: I preferred the older version for: 1. better finger traction on the wheel I find it harder to engage and increased pressure sometimes results in a middle-click being recorded 2. better hand ergonomics It just doesn't feel as comfortable (a larger bump towards the back would provide better palm support) 3. matte surface more difficult to clean Previous version had a shiny surface that was much easier to clean.
Summary: I love this mouse. The small size makes it very easy to pack into a bag for travel, and also makes it easier for me to control. I've gone through many mice, and this one is my favorite so far. The cord is short, which is good for laptops, but would make it difficult to use for desktops.
