Pros: - good for those with bigger hands - great for when it works - magnetic power connector makes charging the mouse easy
Cons: - mouse wheel broke in less than 9 months, now mouse will scroll one more "click" even though you have stopped scrolling, about 5 to 10 seconds after your last scroll - feels slightly cheap on the build quality
Pros: blue-tracking is really accurate, there are 3 speeds which is useful or on the fly switching DPI speeds, nice placement of macro and forward/backward buttons, has a wired/wirelss mode where you can recharge solely by using the "puck" that comes with it.
Cons: only 1 thing..... the recharging contacts for most people become defective within the first month or two. that means you will now have to manually change the batteries yourself so its a bit of pain...
Pros: The mouse is well built, works flawlessly, the scroll wheel is just fine and the dpi switching is superb. Also I had a charge from flat via the cable in less than 12 minutes.
Cons: There is zero chance of any left handed user, as I am, using this mouse. The design is so right handed as to be almost an insult. The back/forward buttons are exactly where a left handed users little finger sits and the bosy is not grippable.
Pros: Lithium battery and charger, additional feet. Programmablilit when it works.
Cons: Mouse Wheel, terrible, forefinger slides off of wheel, wheel get stuck, anything but smooth rotation. Customization doesn't stay, you have to keep re-initiating it. Programmable side buttons rarely work.
Summary: Nice mouse, best feature is the magnetic charging cable. The only reason I never used wireless mice before this one was having to replace or recharge batteries constantly. So, that's good, mouse feels great, relatively high quality. Unfortunately have had to send my first one in because it wouldn't charge anymore, but got a replacement after a few weeks.
