The mouse is visually nice and properly fits in the hand. The principle of storing micro receiver in the battery compartment is very well and avoids losing this one. The small bag is protecting the mouse. It's been about three months since I use it and the batteries have still not been replaced. To the downside it takes some time to adapt to the fact that there is no pure physical button clicks and scroll but I use it daily without worries. The only real complaint concerns the right click that is sometimes hard to get but not really embarrassing. why 4 stars
