Just an update for anyone who is thinking of buying this mouse here is my opinion. I have pretty much all the Naos series mouses and I can conclude that the QG is not worth it. After using it for a while the 2 metal sensors that sit on the palm area have corroded and is showing the copper underneath. I don't really use the app that much but it is fancy showing how many clicks and scrolls you have done on the mouse.
IMHO if you have to pick a mouse regardless of price or features go and pick up the Naos 7000. It is pretty much a QG without the fancy heart rate and click monitor and doesn't suffer from any mouse acceleration.
