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. End of the day, I need more responsiveness and will be purchasing a different mouse in the near future.
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. When I purchased it I wanted something similar to Apple's Magic Mouse. They both cost the same, but Logitech's T620 is far inferior. Do not buy this mouse.
Summary: I'll admit I'm just using this as a regular mouse with Win 7, not 8, not swiping, etc. I thought the mouse surface was just touch sensitive, and you'd tap the surface to "click". But there's actually a button/pad on the bottom of the mouse. So, the entire front of the mouse actually moves down-and-up when you "click". The difference between left and right click is where you're touching the surface when you push the mouse down to "click". Clunky.
Summary: When i got this mouse it worked great for all the simple things i did on the internet. Chrome had an extension that solved the buggy scrolling and all worked. Problem is, you cant remove the receiver from your computer or else you have to re install the driver. Even when it was plugged in, there are times where it just doesn't even recognize that the receiver is plugged into the USB. Id advise looking into another mouse before this one and giving it a try.
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. For example, the mouse click is too pressure sensitive and any hand weight would cause the click and ruin whatever I was doing with the touch surface.
Summary: Bought this mouse yesterday and its going back today. It does randomly move around and the centre scroll is sometimes very unresponsive and sometimes too sensitive. You basically have to remove all but one finger from the surface area of the mouse if you want to click, if you have a part of your right click finger touching the surface, the mouse will left and right click at the same time.

Summary: Logitech peripherals have been my first choice since I first used one of its wireless mice more than a dozen years ago. So the spotty performance of this mouse came as a big surprise...and as a disappointment. As with all of the "gestures" associated with Windows 8 --whether you are using a touchscreen monitor, a touchpad or this mouse--, expect a slight learning curve to master the basic gestures.
The mouse doesn't seem to work well with windows 7 x64

Summary: I wonder if something is wrong with this M620 mouse or it just doesn't work well with Windows 7 Home Edition. The touch scroll is very unsatisfactory. I may have to use this as an expensive wireless mouse which would make me very unhappy. The scroll sometimes works, sometimes not. When it does work it is very erratic and unpredictable. It might scroll up but not down or down but not up. Then suddenly it will start working, maybe with a big jump at first.
