[Expired]Logitech Ergo M575 Wireless Trackball Mouse

: Then you can switch back and forth 然后就又可以换过来用

回复 @匿名用户 : I also use a mouse every day and really need a good one. I checked Amazon, and the price isn't as low as the Walmart one you shared. Is this price pretty stable now? 我也是每天都得用鼠标，真的需要一个好点的，去看了眼Amazon的没有你给我发的Walmart的便宜，这个价格基本就算是稳定的了吧

回复 @匿名用户 : Just search for MX3 to find it. I have tendonitis and want to buy a more comfortable mouse. 直接找mx3就能找到嘛，因为我有腱鞘炎想买个用着舒服点的鼠标

: You can "flick" the ball; that's how I switch screens. Once you're skilled, you'll know exactly when to stop. 你可以“甩”球，我就是这样切换屏幕的，熟练了以后啥时候该停有数

: Trackballs can't change DPI, so it indeed requires several rotations. Therefore, they can't be used with high-resolution or multiple screens. But I haven't tried changing the mouse speed in Windows like the person above mentioned; I don't know if that can solve it. 轨迹球不能改dpi，确实是需要滚好几圈。所以高分和多屏都不能用。但我没试过楼上说的在windows里改鼠标速度，不知道能不能解决

: This is a trackball mouse; the mouse doesn't move, only the ball does. 这是轨迹球鼠标，鼠标不动只动那个球啊。

: You just need to move your fingers. 只是動動手指就可以了。
