Summary: This mouse feels great in the right hand. The trouble is, I'm left-handed. It's like trying to play baseball with a right-handed person's glove. It's all wrong. If you want to see how it feels, just put it in your left hand. Why don't they make a left-handed version if they are going for a contoured mouse? Totally worthless to me. Trouble is, I got it in an MK710 kit and can't return just the mouse. VERY disappointed.
Summary: Not for use with a desktop having tracking issues and sensitivity keeps resetting itself each time you unplug it. not a good feel when moving around with the mouse making it a poor choice for games.
Summary: the ergonomics is great, so is the quality, and the feel of the scrolling wheel. but big tracking issue, probably because bad weight distribution - two AA batteries at the base of the mouse, causing vertical accuracy to be really really horrible. gonna try to return it.
Summary: I bought my mouse and keyboard combo and the keyboard as well as the mouse will frequently drop out and not respond as Im using it. Waste of money in my opinion and not enough support on the issue anywhere to even try to troubleshoot and correct.
Excerpt: I hate this thing. I thought it was damaged so I returned it and purchased another one. You can't even sign onto the computer with it. I had to get my old HP mouse from the trash in order to get online in order to access the Logitech website. That's where I found out that the company wants you to purchase a Logitech keyboard to make sure the mouse works. Or, I could download the company soft ware to see if that helped.
Pros: I Like The Color
Cons: Can't Sign On With It, Inaccurate Tracking, No Response
Summary: I'm a graphic designer/web developer/photographer who is admittedly hard on mice. I'm a female with small hands so this mouse fits comfortably. I love the arrangement and functionality of the buttons. I love the weight. Everything about it is wonderful, except that after about a year of usage, the left button gives out, rendering it useless. I'm on my 3rd one in 3 years and guess what? A few days ago, that left button gave out.
