This mouse is the best mouse I have ever used, hands down. The touch functionality works flawlessly, and makes switching between OS X Spaces effortless and extremely convenient. Scrolling also smooth and implemented nicely. I prefer using the touch surface to scroll over using the "wheel" common on mouses for last couple decades. This mouse is a huge improvement in a tech space that definitely saw some stagnation with regards to innovation. It's going to be hard to beat this mouse outside of someone inventing a way to make air gestures work as well and remove the mouse form the picture altogether.One of the main complaints about this mouse you will read, is that the charging port is on the bottom of the mouse therefore making it unusable while being charged. For anyone concerned about this, it is a complete non-issue. First off, the battery life is excellent. After over a month of fairly heavy, daily use, my mouse 's battery is at 69% as I type this. However, the most important feature in terms of the battery and charging is that this mouse has a quick charge feature. In just two minutes charging time, the mouse will have enough battery life to last 8 hours. That's less time then it takes to get up and go to the restroom, or to get a glass of water. To see your current battery life in OS X, click the bluetooth symbol on the menu bar, select your Mouse, and the current battery strength percentage will be displayed. I would much rather have the rechargeable battery than to have to by batteries for my mouse.The tracking on a variety of surfaces works excellent. I currently use my mouse on a black wooden desktop with no mouse pad, and it glides smoothly and tracks smoothly as well. It also works nicely on my tan couch, on my pants legs, and a leather ottoman.The "clicking" is positive and provides good feedback. Tapping on the surface instead of using a "full click" also works very well.There are a number of settings you change for the mouse in the OS X Settings. For example, I have the touch surface set to Zoom In on whatever I am viewing if I double tap the right side of the touch surface, which is great when reading the news (or reviews). Zoom out by double tapping again.The mouse comes packaged in typical apple fashion, in a nice compact box. The mouse comes with a brief getting started manual, a lighting charging cord, and two apple stickers.If you have any questions feel free to ask.
