I needed a quick replacement computer. Mine crashed one week before home school was to start.  I read all the reviews and found that this one would do all that I needed for now.  It is renewed and that was a concern. It should not have been. So far, this machine does everything that I need it to do and it is working great.  It is very fast.  The only thing that might be a negative is the sound. It reminds me of a coffee pot type noise.  Like all other things we ignore this small noise and continue on.  I do plan on purchasing a new computer for my personal use.  This computer will continue to function as a home school tool.  Set up was very easy.  I like the small size of it.  It has enough USB ports to do all that is needed.  However, it does not have a sdcard reader slot.  That's an easy fix with a plug in.  The price was really good and the speed and storage on this unit are more than what I need right now for home schooling my grandson.
