Query: Outstanding Product!!!

I purchased this product after carefully reviewing several options. After all, this would be my first experience with a wireless mouse and I did not want to be disappointed. I considered online reviews, overall ratings, and price at a variety of online vendors. I even visited my local computer store to consult with the salespeople there. My laptop immediately recognized the USB receiver and I have been in operation ever since without any blunders. There is no lagging in performance and it even has a battery-saving feature. FYI, the size of this mouse is for average to large-sized hands, so if you want a tiny or compact mouse, this is not the one for you. Even after you consider its larger size-if this is even an issue- this mouse still demands special consideration due to its multi-button features (4-way scroll with tilt wheel, page-forward & page-backward). I highly recommend this product!
