"Extremely satisfied; best mouse ever."5.0 starson by prodo123
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!!!
