Summary: The mouse is well built but the software driver is terrible. The scroll responsiveness is terrible, right click or left click work when they want so much so I just basically used the mouse as a backup, but do yourself a favor do not buy this.
Summary: I swear by Logitech products. Since my 1st computer I bought, all mice and keyboard purchases were Logitechs (currently sitting at 9 Logitech products). This was something new and I was curious how a touch mouse would feel when using Win-7. I regret the purchase. I was 15 minutes late to work today.
Summary: I saw this mouse in the store and decided to give it a shot. I am a software engineer and use this mouse daily. I am running Windows 8, 64 bit and have the latest drivers. My biggest problem with the mouse is scrolling. It just doesn't respond well enough for me.
Summary: Logitech is a great company but they have had some pretty poor products of late. Be cautious when purchasing any new Logitech products especially the Harmony line and this mouse.
Pros: It left clicks and right clicks....just not well.
Cons: I'm amazed how this can be the same cost as a Apple Magic Mouse yet this be far inferior. Every one of the special features fall far short. This Logitech mouse looks cheap when placed next to an Apple Magic Mouse.
Summary: The only reason I can't justify giving this mouse one star is that it does what a mouse should. It left clicks and it right clicks...it just doesn't do either well. I've owned this mouse and used it 8 hours a day at work for 6 months. Please avoid this mouse. It is garbage.
Summary: The idea is very good. Combining touch with conventional mouse movement for the PC and do for Windows what the mighty mouse did for MAC. However, there are too many twitchy problems with the interface that don't allow for enough natural hand positions which would often cause unintended errors.
Summary: The touch-based features are unreliable, and give no tactile feedback.Scrolling is awkward and not as positive as a wheel. Trying to middle-click often results in a left-click. The Windows 8 features are of little value. I trigger them accidently more often than I use them intentionally.
Summary: I was very sceptical about using a touch interface on a mouse for clicking and scrolling before purchasing this mouse. I wish I had listened my gut feeling and saved myself some money. First the good things about this mouse. The mouse is very nicely shaped.
