Some nice customisation options but patchy performance - avoid!
on 3 July 2013
I'm a huge fan of Logitech, I think that (overall) their stuff is great value and well-made. Sadly, they've dropped the ball with this mouse. I work from home and after spending 4 days using this mouse I have 2 main issues:
1) Patchy and intermittent tracking
This may be more of a failing of the bluetooth technology, rather than this specific model of mouse, but it's a fatal flaw either way. For example if I move the mouse cursor from the far right of my monitor to the far left it will stop tracking and suddenly 'catch up' after half a second or so. Though this happens only sporadically (maybe once every minute or so), it is infuriating and I have lost count of how many times I've clicked on an incorrect link or icon during the 4 days I've owned this mouse. I've tried using it on a black mouse mat, white A4 paper and on the wood of my desk and the issue persists on all surfaces. This is obviously a deal breaker and is the reason I've returned the mouse. If you are about to buy a bluetooth mouse for the first time, be aware that you are not going to get the level of 1:1 control that you have previously taken for granted with a wired mouse.
2) There is no middle mouse button click
Despite an abundance of customisation options, it is not possible to use the middle mouse button as a 'click'. Pressing the middle button down toggles the scroll wheel between 'click mode' and 'freewheeling mode'. I spent a good 30 minutes fully exploring the customisation options to try and map a middle mouse button for 'click' and, strangely, it's simply not possible. I frequently use the middle button to open new tabs when using internet browsers, so this is another black mark. (It is possible to map the click to a left or right middle mouse button tilt, but I've spent 20 years pressing the middle mouse button and I didn't fancy relearning this particular piece of muscle memory!)
I've returned this item and bought a Logitech G500.
