I bought the product a few months ago, and I love it.  So I bought another.  That one shipped to me with defective video.  The replacement also shipped to me with defective video. So 1/3 of the ones I've sampled are five star, and two are one star.  So I have to give this product two stars. If Amazon.com gets on their supplier to check their quality control on this system, it'd certainly be a great purchase.  Otherwise...
