Granted, this is a 140.00 computer, but rhe ad states that everything is tested blah blah blah, the mouse doesn't work, the wireless adapter wasn't included, and 3 keys fell off the keyboard when I took it out the package. I snapped the keys back on, no big deal, but now I have to wait no telling how long for the adapter and mouse. If was almost 2 weeks for the unit to begin with so we will see what happens.*Update* changing to 4 stars from 2. They sent the missing wireless wifi adapter and 2 replacement mice and received the next day. If you have an issue, they will promptly make it right. Thank you.
