Depends which spindles you buy...
At first, I bought a couple of 100dvd+r spindles, the ones that were not completely printable and they worked awesome. Almost 100% efficiency at 1$ a dvd. Then I purchased the ones fully printable worth .60cts each. These Stunk Big Time. I had at least a 25% failure ratio. These should be taken off the market and replace them with the more expensive ones. Suggestion, Don't buy them. You'll hate yourself.
