3.0 out of 5 stars Well designed touch mouse, lovely feel, good for Windows 8 but annoyances too, 27 Dec. 2012
This review is from: Logitech T620 Touch Mouse - Graphite (Accessory)
Customer review from the Amazon Vine Programme (What's this?)
The t620 is a wireless touch mouse. A "touch" mouse is so called because the surface of the mouse is touch-sensitive so that you can perform finger gestures that execute special actions in Windows - and yes, this is primarily a Windows mouse, though I tried it on a Mac and it worked fine for basic mouse pointer movement, right and left click, and scrolling. It is also optimised for Windows 8, though it works well on Windows 7 as well.

The packaging is a tad extravagant, more of an in-store display unit than a box, but it was easily unpacked. You get the mouse, a USB receiver that plugs into your PC to connect the mouse, two Duracell AA batteries, and a small drawstring bag.

Although it takes two batteries, the mouse will operate fine with just one, so I imagine the purpose of the second battery is to extend battery life.

Getting started is a matter of plugging in the receiver, inserting the batteries, and switching on the mouse. It worked instantly, though Windows 8 also popped up an installer for the Logitech SetPoint software. The software is needed in order to use all the gestures and access the settings.

If you have a tablet with only one USB port, it is annoying to fill it with the receiver, but this is mitigated slightly by Logitech's Unifying receiver which means the same receiver will also work for a Logitech keyboard.

The mouse itself is lightweight with a smooth glossy finish and highly responsive surface. Note that there are no buttons as such, though the point where the buttons would be is clickable. If you click on the left you get a left click, on the right a right click. If you stroke your finger back and forth vertically, you get scrolling as with a scroll wheel.

The SetPoint software is well done. You can enable or disable specific features, configure settings like scroll speed and inverse scrolling, and in addition there are small video demos of each gesture. There are seven gestures in all:

- Double-tap for Start screen
- Show/hide desktop
- Switch applications
- Show Charms (the right-hand Windows 8 menu)
- Vertical scrolling
- Horizontal scrolling
- Back/forward in web browser

No pinch to zoom, sadly.

Any problems then? A few things worth mentioning.

First, the mouse is flatter than most others, so does not fit snugly in your hand like most. I did not mind this, but a mouse is a personal thing and it may not suit everyone.

Another is that some of the gestures take some practice, especially the ones that need two fingers. The Touch mouse is sensitive and responds best to light taps and strokes. I found the double-tap for Start screen difficult until I tried very light taps.

Another issue is that you may sometimes trigger an action by accident. I always disable "tap to click" on a trackpad for exactly this reason. Tap to click is not a problem with the Touch mouse, since only a physical click works, but when web browsing I do occasionally trigger back or forward by mistake. Of course you can disable any troublesome gestures if they do not work for you.

On Windows 8, I particularly like the Show Charms gesture (swipe finger from right), since this menu can otherwise be awkward to show using the mouse.

I found the mouse speed too fast by default, making it too easy to overshoot your target. This is easily fixed in the configuration software.

Overall: I like it, and it is a particularly nice add-in If you have Windows 8 without a touch screen.

Update: on the basis of longer use I've removed a star from this review. While it seems a lovely mouse at first, I have found that it is too fussy and unpredictable. Specifically, scrolling is problematic; sometimes you stroke the mouse and nothing happens. Another issue I have encountered is getting a right-click instead of a left-click; somehow the mouse detects the exact location of your click wrongly. Third, I sometimes use a mouse left-handed (to reduce strain) which with this is a disaster, not because of the left-handedness as such, but because with my less preferred hand my palm brushes the surface and causes unexpected actions.

Clearly designing a great touch mouse is harder than designing a conventional mouse, with many new issues, and despite the elegance of the T620 there are too many annoyances for me.
