I’m sure some of you – at least if you own the MX1000 – know that it can be annoying when you’ve forgotten to charge the mouse - you come to use it and the red little light flashes up telling you that you’re out of luck. Logitech has solved this problem by supplying the G7 with two removable Li-Ion battery packs. These are flat squares that slot into the bottom of the mouse. To remove the battery you press the eject button and it just pops right out.
The charger plugs into your USB port, much like a normal cordless mouse receiver and has a slot for one battery. Again, this has an eject button that releases the battery. The top of the charging station has a USB port to which you can fit the receiver. This might seem like an odd solution, but for those that attend LAN parties regularly it might prove to be a handy feature – allowing you to only bring the small USB key with you instead of a large lump of plastic.
The bottom of the charger has a switch for fast or slow charging, although I’m not sure why anyone would use the slow settings. According to Logitech it takes about two hours to fully charge one battery in the boost mode. The bottom of the mouse also features an on/off button, so you’re not wasting battery power when the mouse is not in use.
As I mentioned, the G7 has lost some features of the MX518, most noticeable is that one of the side buttons is missing. This means that in Windows you only have a back button in your web browser. This has been done – according to Logitech – because hardcore gamers don’t like to have too many buttons on their mice, but to me this sounds a bit daft; you can’t have too many programmable buttons in my book. Also gone is the application switching button – not as big as a loss – as it had to make way for the dpi adjustment buttons, as both are now below the scroll wheel.
