Summary: This thing is all looks. It performs poorly, there is an obvious lag and the entire connection freezes up every few seconds! And I know that this isn't just me having this problem as I have read other professional reviews on other sites and they say that they just can't give this model a good review...
Pros: Pros, uh gee let me think, since the only thing that matters about this mouse is horribly flawed none of the other potential "Pros" even matter.
Cons: Connection freezes every few seconds Buttons don't respond Lag
Summary: This is a beautiful and robust mouse with great design but does not work. It would be the perfect mouse if only it was responsive.
Pros: The mouse is great in concept:
-The free-scrolling button is amazing; you hold down the button and then you can scroll by moving the mouse itself which gives you complete freedom to scroll in any direction.
-Programmable thumb buttons
-Does work on glass
Cons: The mouse completely fails in execution:
It is simply unresponsive. It works 99% of the time, but that is unacceptable for a mouse. Sometimes the mouse disconnects during a click and will register as being held down. Sometimes it will cut out for some fractions of a second. All the time it is lag...
Excerpt: I bought this mouse back in October and unfortunately from the first few hours spent with it I have been really disappointed. It looses signal and constantly interrupts and inputs you do to complete any task. I'm using it no more then 1m from the receiver with no solid obstructions.
Summary: The worst mouse i ever owned. Replaced it due to lack of sensitivity after 1.5 month lost entire connectivity. Cursor did not move. Applied all basic troubleshooting but no chance. Now it is happening again with replaced one as well, i guess this product has got some serious software issue.
