The price is currently hovering around the $70 mark, being marginally over this price from a number of outlets, putting it at the maximum limit of this question's price range.
Once fully charged the mouse lasts for several weeks of moderate use before requiring further charge. Users are notified through lights on the mouse itself, and systray notifications when the mouse is nearing the end of its charge (generally several days before).
Even after several years of use this appears to be the case.
The mouse uses one AA battery. A rechargeable NI-MH battery is included. The battery compartment is easily accessible, requiring no tools to assist.
The Logitech Unifying Receiver allows you to connect multiple (up to 6) devices through one single, small dongle. The dongle itself is made up mostly of the USB connector, meaning it's small and so stays out of the way, and is unlikely to be bent or broken if knocked.
Hitting a button behind the scroll wheel changes the scroll wheel from clicking up and down in a controlled manner to allowing you to flick it and quickly scroll through large portions of a document.
Three programmable buttons are easily accessed by your thumb.
In addition to the Zoom, Forward and Back buttons depicted, the thumb rest has a button for switching between applications, the mouse wheel may be held to allow drag navigation, and the mouse button may be tilted left or right for horizontal scrolling.
All of these buttons can be configured per application via the bundled SetPoint software.
Though the mouse works wirelessly, it's recharged via USB. When recharging, the mouse continues to work .
NB: The mouse still communicates wirelessly, so requires one USB for the Logitech Dongle, and one for the charge cable.
A commonly reported fault is that the mouse's main buttons occasionally cease to function, or double click when only a single click is intended.
However this is easily resolved by removing the batteries and pressing all of the buttons to allow the mouse's capacitors to discharge.
The overall build quality is sturdy enough to withstand many drops from desk to floor and the jostling of being carried around during travel with checked luggage without developing any rattles or loose buttons.
This is good for those using a laptop or other portable devices as the dongle is low profile and does not protrude that much when plugged in, meaning it wont snag on thing while carrying the device around or look unpleasant.
Problems with clicking the buttons after 6 months of continuous daily hardcore gaming use, happened 4 times in a row (good thing there is 2-3 years warranty).
There have been a few users who have reported getting used mice when purchasing new ones as they come dinged up and looking old. This is through the manufacturer on Amazon, may not be an issue ordering elsewhere if it is coming from a third party.
