I would have given 5 stars, but it quit yesterday after about 4 months use.  While working, it did everything I expected very well.  However, when I turned it on yesterday, it did not load up and would not shut off.  I unplugged it, waited a minute and plugged it back in.  It came on immediately without using "on": button(?), still would not load, and won't shut off with "on-off" button.  I repeated this process several times, waiting over night with "unit of" for last try.  It is now just a small paper weight.
