I bought this to replace one just like it which was having various problems. I've used it for years and it's been an armchair companion.  The unit I received from Amazon (?) seemed to run slower than what I had.  Granted I had windows10 pro on the old one, and the new one had windows10 home edition.  I don't knoiw if  the PRO release made it run faster, but it was definetly faster than the one I received.  I have since fixed one of my problems and found a work-around for the other. Still chugging along.
