Query: HP products--TOPS

I've used several hundred of these HP- DVD-R's, with cover art inkjetted from the HP D7560 printer, which makes excellent copies that compete with the high end commercial discs.As an indie filmmaker, I'm very pleased with the color of the printing, clarity, and speed. The discs are also very highly reliable in recording, with a less than 1 percent failure rate , (which may be due to greasy-thumb-itus on my part).As usual HP makes world class products. Will not buy any others.
