With all this nifty gear stuffed into it, you might think the mouse is a little oversized for a travelling companion. But in actuality, it's one of the smallest wireless mice I have reviewed; maintaining the delicate balance of being small enough to slip in a laptop bag, but at the same time still fitting comfortably in the hand.
As can be seen in these pictures below, the comparison in size to Microsoft's Explorer Mini mouse shows that this mouse is a much tighter package to one of its main rivals. However, I prefer the rubber grips of the GM-M7700 as it gives the mouse a much nicer feel when being held for long periods of time.
Firing up some games like World of Warcraft to play for a couple of hours and we can see that the laser tracks well and there is no hand cramping that is usually associated with the half sized rodents.
Plugging it into my HTPC, the mouse is good up to 10 meters away and this is certainly well specced; there was no lag or drop out in the signal while navigating around my movie collection.
Getting into precision work is where the dual DPI system comes into its own. As an electronic engineer I sometimes need to make tiny precise movements when designing circuits and having the ability to switch between faster and more precise tracking is a god-send!
In conclusion, I would say that this mouse is a firm favourite for travelling with, due to its smaller package, comfort and multiple DPI settings. So don't be afraid to splurge a little next time you are looking for a good wireless mouse.
