Bests & Worsts Reviews from Amazon

I've been using this updated version of the Anker Ergonomic Wireless Vertical Mouse for a few days, after having owned the previous model for 7 months. The newer model is definitely superior. The biggest improvement is that the new shape is smoother and more comfortable. My hand is more relaxed when resting my thumb above the back/forward buttons, but the previous model had an obstructive edge on the left side that I am glad they've removed. Other changes in the new model include a small protective lip to protect pinkies from dragging on tabletops, and a different location for the DPI switch. I never had problems with pinky dragging or accidentally hitting the DPI switch in the old model, but I still appreciate both of these minor improvements. Another change is that the direction of the scroll wheel's middle-click has been reversed in the updated version. In the old model, you apply left-ward pressure to the scroll wheel to middle-click; in the new version you apply right-ward pressure. I find middle-clicking easier to use in the old model, but this is a minor concern, and I've already adjusted to the new mouse. FYI the decorative stripes that are supposed to light up with red LEDs are never as vibrant as pictured. The stripes on the inside curve only flash when the mouse is turned on; after you begin using the mouse, they turn off completely. Overall an excellent mouse for its comfortable, ergonomic shape and cheap price. Plus, at the time of writing this version costs the same as the old one.
