Summary: Excellent media for making backups and storing important information. Manufacturer code is MCC004, which is considered first quality (or best available quality). If you find them on sale (or need to make reliable burns) then don't hesitate to buy.
I've bought other cheaper (unknown) brands and quality has been third or fourth (the worst). Don't waste your money and buy Verbatims.
Verbatim changed to other manufacturer for a short while, but went back to first quality. No regrets in buying from them today.

Summary: This is my preferred DVD brand. After trying Imation, Maxell, GQ, Sony, Ridata, OfficeMax, Office Depot, Nexxtech, memorex, and others, I will stick with Verbatim. simply put, it saves time, expense, and difficulty with trouble free, reliable burns. Another significant difference is that this product carries a limited lifetime guarantee, which many other brands do not.

added note: If you have a choice, the 50 pak containers have
given me better results than those packaged in the 100 pak, but this is more applicable to the DVD-R16x. The DVD+R16x is more consistent between the 100 pak and 50pak versions. What you need to look for are scratches on the underside of the media toward the outside edge and flaws in the dye visible with the naked eye with a flashlight in the 100 pak. So far, with the 100 pak dvd+r16x this has not been a problem, but can be with the 100 pak dvd-r16x. I offer this for comparison purposes, as I have found the +R to be consistently better quality than the -R in 16x.

Summary: I have burned about fifty of these disks without a single problem. Verbatim is one of the best companies for writable
media and this product lives up to the expectations. These disks burn reliably at 16X and have a nice silver surface with lines for labling.
