Never ever buy from this supplier.  We received the product and both the keyboard and mouse never worked.  Could not connect to anything.  Went to get a functioning keyboard and mouse and it wouldn't connect.  Even the help button shown on the screen did not work.  I tried to believe that there must be some level of integrity by Amazon partnering with suppliers like this, but I guess I was wrong.  I have never had to write a review on anything from Amazon, but the hassle this has caused me is tremendous.  I am also hoping they will refund my 3 year warranty program that I also bought.
