[B][I]The following is an independent rating in Amazon. This and other comments can be found under "more buying choices" in the selling details>>"Dual Layer DVD's are harder and harder to find. It's almost impossible to find them on sale anywhere. I was excited when Amazon introduced this Baiscs program and included Dual Layer discs in the mix.
The discs do not disappoint. A spindle of 50 arrived in a nice neat cardboard box. The packaging was easy to open, except for destroying the packing slip while opening. The spindle is a 'cake box' type, and it seals up very nicely. The outer shrink wrap is clear plastic. The DVD+R DL you see in the picture is a paper wrapper around the discs inside. Fortunately the DVD+ DL words are printed large and in dark black ink on a silver background on each disc, and the cake box is crystal clear. If this hadn't been the case, it would be extremely difficult to identify which discs are inside (I have spindles of four different single layer manufacturers, and two other dual layers).
The first question I had, do they burn at 8X and do they work? Well a good solid resounding yes they do burn at the published speed. They do work well. They are not a magic silver bullet. I have a DVD player that refuses to play any dual layer discs; I've tried Sony, Verbatim, Memorex, and now Amazon Basics - none work at all on this player. However, the Basics disc does play in players that are happy with dual layer discs.
The critical question everyone should have on their mind - the manufacturer. Pretty simple to fire up DVD Identifier; and voila RicohJPND01, revision 067. That should make everyone fairly happy. They fall exactly in the class of DVD blanks with Sony and Memorex - dual layers (the Sonys I have were moserbaerIndiaMBIG101's), not the first class grouping.
I'm very pleased with these discs. Any time I can find Dual Layer discs for under one dollar each, I'm happy. These fit into a very sweet spot of media quality and price per disc. If you need dual layers, this is a good place to purchase.
September 28, 2009 - Burn number 10, not a single flaw yet. No failures, no disc problems. For the record, my two DVD burners are under 1 year old, with current firmware, and are both manufactured by TSST corportation, Models S203N and S223Q, Samsung burners. Product links for my burners: 20X DVDRW DVD Burner - Black SATA, and Samsung SH-S223Q/BEBS Internal Half Height Supermulti SATA 22X Lightscribe DVD-Writable Drive" Other comments differ
