After the Touch Mouse M600, Logitech is back with the Touch Mouse T620, a wireless touch-sensitive device with functions tailored specially to Windows 8.

Design3/5


Logitech hasn't changed the shape of its Touch Mouse, so the T620 feels just like the M600 to hold. This mouse can therefore be used by left- and right-handed users, and there are no physical or virtual thumb-buttons on the sides of the casing. We tested the iridescent, pearly white version of this mouse, which, unlike the glossy black model, doesn't show up fingerprints too badly.

The mouse's dimensions haven't budged. The T620 is 11 cm long, which makes it comfortable to handle even though it's not long enough to support your wrist (which is recommended by occupational therapists but not always appreciated by users). The two AA batteries on the inside give the mouse a decent but poorly balanced weight. The back of the mouse is heavier and tends to skid a bit when you make fast movements.

The T620 has no physical buttons but the touch-sensitive surface offers plenty of controls. A sensor built into the casing recognises certain movements and gestures so you can do much more than just a left or right click.

The various gestures and controls are all outlined in detail in a series of videos on Logitech's website. You can scroll horizontally and vertically (notched or smooth), zoom in and out, and move forwards and backwards a page (as usually controlled by thumb buttons). Pressing the top of the casing twice minimises all your windows for fast access to the desktop. These functions will be completely useless for image editors or gamers but they'll be very handy for office computing and surfing the Internet.

A whole load of extra functions are available to Windows 8 users, such as switching from one app to another with a simple finger movement. Note, however, that you'll need to install Logitech's driver for the PC to recognise these movements. Without it, you only get the left and right click functions and the virtual scroll wheel.

Logitech Touch Mouse T620 review - laser sensor usb dongle

The mouse communicates with your PC via a small USB receiver. This sticks out barely half a centimetre from the USB port when connected, so you aren't likely to knock it out by accident. However, its small size does make the USB receiver quite easy to lose, especially when on the move. That's no doubt why Logitech has included an onboard storage compartment for the receiver just next to the batteries.

Precision3/5


The polling rate of 125 Hz won't be fast enough for hardcore gamers but it's perfectly fine for occasional gaming and office computing.

Logitech Touch Mouse T620 review - speed
A gaming mouse needs a sensor that can track movements
of at least 3 metres per second
.


And, if that wasn't enough to put off gamers, the fact the T620 can only track movements of up to 1.2 metres per second probably will be. That's nowhere near speedy enough for fast-action FPS where every split-second counts (Call of Duty, Half Life, etc.). However, it won't be much of a problem in other kinds of games or applications.
3/5 Logitech Touch Mouse T620 DigitalVersus 2012-11-14 10:02:00

Pros

  • Small, discreet USB receiver
  • Several Logitech wireless peripherals can be synced to the same USB receiver via the driver (see inset)
  • Touch-control virtual scroll wheel for notched or smooth horizontal or vertical scrolling
  • Suitable for left- and right-handed users

Cons

  • Low maximum movement tracking speed (1.2 m/s)
  • No thumb buttons
  • DPI can't be adjusted on the fly (for gamers)
  • Too small for ideal ergonomics (11 cm long)
  • No built-in recharging system (AA batteries)

Conclusion

With the Touch Mouse T620, Logitech is back on par with Microsoft and its Explorer Touch Mouse. However, this mouse is only really suitable for office computing and web browsing.
