This was not an inexpensive item and worked well for about 10 months.  Then the dreaded insert boot media error message and surprise, no support!  Their website is dead.  You can buy the domain name...  It's too bad because this seemed like a good unit but it needs to last longer than 10 months.  I've tried to leave questions on the product page but no help.  Look for a different supplier that stands behind the product.
