Pros Works on so many surfaces,
small USB receiver,
fits well in hand
Cons scroll wheel doesnt click...
Summary This mouse is amazing! Search the internet for cheaper prices than large retail electronic stores sell it for, I paid well under half the price online! Works great, fits perfect to right handed users, if only the scroll wheel clicked....UPDATE: As much as I love this mouse, I am extremely disappointed with the battery life recently. Within the last 3-4 months the mouse has started to eat up batteries like crazy. I only use high quality rechargeable batteries, as well as the one that originally came with it, and it will not hold a charge at all.

Pros Ergonomic design; feels like an extension of your hand. Floats like a cloud on a mouse pad, works very well on any colored surfaces including white, red, blue, yellow, and black.
Cons Though I am a righty, I see why people would complain about no lefty support. The charger dock is a bit shaky, but negligibly. Scroll wheel feels a tiny bit awkward.
Summary Superb mouse. The USB dongle is a tad bit bigger than I would've wanted, but still smaller than what I expected (I was thinking of a full USB flash drive-sized dongle!). The tracking technology is great. It feels like, well, a blue-glowing cloud because of the refrigerator-magnet-like pads to minimize mouse friction. When it comes to lefty support, the 4-button mouse might accidentally click the backwards or forwards button with the ring finger. However, if you get used to avoiding the buttons, it might not be a big problem. Perfect for carrying in a laptop case while having the dock at home next to a desktop. Now I have a single mouse for 2 computers!
Bought for $20 during a sale. Extremely good price!!!

Pros Feels good in my large hand, comfortable to use, works on any surface.
Cons Scroll wheel is a but mushy, but not a real problem
Summary I received this mouse as a replacement for a broken Laser Mouse 8000 under warranty, and I prefer it to the original mouse. Microsoft has the best mice products and provides exemplary service for them in my experience. And this is coming from a die-hard Apple Mac user!
Pros Very light, easy to use on mostly all surfaces. Light, and rechargeable :)
Cons The USB connector breaks WAY too easily.
Summary Great product, just needs a solution to the USB problem and the mouse would work perfect. Luckily, their online support is great and they sent me a new one for free, which just recently broke. Now i'm on my third mouse, which is being shipped to me right now. THIRD MOUSE! Thank God they are free.
