Pepst, don’t worry, I don’t plan to use them to displace my stock of Maxell single-layered DVD-R as I find they are much more difficult to burn (setting up, knowing layer changes, etc) and I find their price, understandably double single layers, a bit of a setback. Less discs for same price.
Rather have my AVI Rips / Data / Whatever stored on several Single Layered Discs rather than a dual layer because not all burners can read DL discs, and if one disc goes down, it doesn’t take out all of my data.
Maxell RitekF1, best discs used so far. Very very reliable!
