I had recently upgraded to the Toshiba SD-R5112 Drive, and it has the capability to burn at 4X. I had previously purchased the 1X Princo media from this seller and for the most part they were OK (one batch I ordered had MANY bad discs, close to 25% now give read errors). But these Blank DVD-R's were supposed to be 4X. The software I used can burn at 4X (Latest version of Stomp RecordNowMax), I tried at least 5-6 of these 100 that I had ordered, and all of them only burn at 1X, Not even 2X. So needless to say I was fairly upset. I decided to contact them and right off the bat they automatically started putting the blame on the software, my drive, or the capabilities of my computer system, which is all complete BS. Because I had purchased several different brands of 4X DVD-R media from different places locally and they all burned at 4X fine. So the solution they said was for me to pay out of MY OWN pocket to ship this media back to them so that they could "test" it out. I refused because why should I pay for something that is being falsely advertised, the two options that I thought were more than fair was for them to pay for shipping of this media back. Or to simply give me $20 store credit to a future order since this media only works at 1X (1X media was about $20 less for a pack of 100). They refused.
So basically I'm here to say, STAY AWAY from AllMediaOutlet.com a perfect example of why the place with the best price doesn't always equal the best deal, it's better to pay a bit more and go somewhere that actually has some type of customer service.

That shows I'm not the only one that feels the same way!
