If you are looking for "up to 16x DVD-R" this product would have been a GREAT buy. The problem is that right in the title it states 4X *Not up to 16X". My DVD recorder is NOT compatible with anything but 4x and below. I specifically purchased this product to get 4x DVD-Rs. This is NOT what I received and I had to return them.Amazon was great on the return. There was no cost to me and the refund was processed quickly.Bottom line on this product - IT IS NOT 4x DVD-R MEDIA AND SHOULD NOT BE SOLD AS SUCH.
