When I received this product and took it out of the Amazon shipping box, I started to read the outside of the product's box.  I was startled when I quickly came upon an incorrectly spelled word.  I was worried that if the manufacturer did not proofread their materials for a product that costs as much as this does, what was the chance their product was of high quality?  Well, so far, after several weeks, everything is operating as described.  I'll revise this review if I encounter any problems.
