Title: Annoying
Review: The side buttons are hard to use, because it's hard to press on one of them without pressing another button at the same time.The mouse goes into power savings mode after 1 second of inactivity, giving a very slight but noticeable delay before the pointer will move. After 15 seconds, the delay is even longer and more noticeable and annoying, and after 1 hour, you have to click a button to wake the mouse up.The motion seems to be jittery occasionally, and it's hard to adjust the pointer to a satisfying speed and acceleration. It's either too fast or too slow.On the plus side, the scroll wheel is quiet and has a nice feel to it.Spend an extra 20 bucks and avoid the annoyances.
