Query: Does not work properly, email 4 times never answer. not recomended

Less than a week after I purchased, the mouse did not work properly, try everything, change batteries 3 times and still does not work. receptor is 2 feet away and give a lot of problem. Email the supplier 4 time and never answer, he does not care about warranty or service, do not recomend any one to purchase from them.
