WORST PRODUCT EVER. I HAVE 3 DELL COMPUTERS LIKE THIS. BUT RENEWED ONE IS AWEFULL. IT DID NOT HAVE WORKING ACCESSORIES WHEN IT ARRIVED. THEN AFTER SO MUCH ARGUMENTS A NEW MOUSE WAS SENT. IT WOORKED FOR 2 MONTHS AND NOW IT IS ALL GIBBERISH. I WORK ON COMPUTERS ONLY TILL APRIL 15 EVERY YEAR. I STARTED RENEWED ONE ON DEC.10 AND IT COUND NOT BE PUT ON. MOUSE DID NOT MOVE THE CURCSUR. SO WHAT NOW?
