Got it up and working in a short period of time. I had to hunt online to find the correct bar code to print out and scan in order to change one of the defaults, and it would have been easier to have that provided in the documentation that was packed with the unit. But in all other respects, I'm pleased with the unit, which works as advertised. Because it will be used regularly "in the field," I added in Overstock's three-year warranty, to maximize its working life, at a good price. A great purchase at a good price.
