bad mouse

What I expect of a wireless mouse is that it works where I am. It is a selling point for the manufacturer who said, "The Laser precision fluidity of movement on almost any surface" in tiny even when it is specified that it does not work on clear glass I myself care a bit if I'm not going to require the rest very well. After a few days of use I can attest that this mouse gives me satisfaction when the support used is my shirt, my pants as my mouse pad, but on my couch and my coffee table varnished wood NIET it works very badly and evil, there contrary to what the manufacturer says I am very frustrated and sometimes I'm a little upset; Progress underperformed my first wireless mouse that was of the same mark and that it posed no major problem /
The keyboard no complaints, multi media keys are well placed and practices, there is an indicator for caps lock on.
Still just a word to tell you that my old Logitech mouse without wire does not communicate with the Logitech Unifying receiver.
