This is the second one I purchased within the last month.  I was so pleased with it that I ordered another for my sister-in-law, who needed an upgrade.  The all in one has the best features.  When she received hers, and realized that it did not function, even without the power cord and wifi adapter, she began to notice that there were cracks in the monitor area and the back plate was cracked and became open.  I tried to advise the sender but no luck and after a frustrating period we both gave up.  I wish there was another, similar to mine,  as it has all the features needed.  Be Safe,  Jerry Costa
