Norazza DD3001 Data Destroyer CD/DVD Shredder

So far it works great, have destroyed at least 1,000 DVD’s and CD’s over the last month. You just put the DVD thru the opening, one at a time – the machine makes some noise and makes a pattern of scratches on both sides and covers every inch to make it unreadable. Takes about 5 seconds a DVD. I haven’t pushed it to fast; so I have had no issues with overheating and such – I wait about 5+ seconds before I put the next one thru.So far very happy with the purchase and far faster and convenient then using our old Paper Shredder. Also, it rather small so doesn't take up much space, it's about half the size of a shoe box.

For the price, it's worth using to physically destroy any type of optical media. This unit will punch holes on the top and bottom of the optical media rendering it impossible to read from.Only complaint is it can be a painstaking slow process as you feed one optical media after another and the shredding sound it makes can be annoying

It worked great for about 3 months and then it stopped working. It has some kind of eletrical shortage.

Purchased this item to destroy disks. It worked great for a while, then just died on me. I did not overly use it, as I spaced out my disk destructions to about 4-5 a day. I followed the instructions concerning unplugging. Still the unit died on me after just over year of use. And believe it or not, I didn't even use it for the last month or so prior to it dying out on me. I certainly would not recommend purchasing this item.

Fast, non messy, makes the disc unrecognizable in a disc drive. I would say the noise is about the same as most shredders (when doing paper). Also has a built in cool down period if you do too many disc without giving it a rest (auto shut down until it cools off). Cool down period is 5 mins (according to the manual) then you can start to use it again, wish I had a shredder with that feature. Overall I think this is worth the money if you have some disc you want to throw away but don't want just anyone to be able to read them, not sure if someone (providing they had the time and money) could retrieve anything, but for discs that have real sensitive information you can run them through this thing and then take more drastic measures before throwing them away (as a double measure). Sometimes it is good to be extra careful. I have to thank the reviewer for the pictures of the discs after running them through this thing (the pictures are accurate) but to put it to scale it makes tiny little rectangular notches that you can actually feel with your finger with a space between the marks of 1/16".Important Note:As an extra step I separated a DVD (taking apart the two plastic discs) after running it through this machine and there were no marks on the metal coating. It DOES NOT puncture the metal coating on a DVD but rather the marks go into the plastic sheets (most of the way) but even the inside of the plastic sheet did not have any holes in it. In other words the marks were only on the outside of the discs. Another way to think of it is like making small notches in the bread of a peanut butter and jelly sandwich that do not go completely through to the peanut butter and jelly. Now on a CD it would effect the metal coating since a CD has only one plastic disc with the coating on one side and a DVD has a metal coating sandwiched between two discs. To be fair though, in my opinion, it would be extremely difficult to separate a DVD without damaging the metal coating on the inside since it tends to flake and fall apart easily as it did when I took one apart. Even if you could take a DVD apart without damaging the metal coating I am not sure you could read the disc with the metal coating being exposed like that (at least not in a standard disc reader). But as I said earlier if the info is really sensitive I would not just run it through this device. Hope that helps.

This is a great little product! It is smaller than I expected and fits easily in a corner on your desktop. I had a stack of CD's with recordings of customer service phone calls that needed to be destroyed (HIPAA protected electronic protected health information (ePHI)). This little product did the trick. One pass through indents both the front and back of the CD/DVD with thousands of little indentations that supposedly make the CD/DVD unreadable.One pass takes about 6 seconds to destroy the CD/DVD. If you feed the CD/DVD's quickly one right after the other you can destroy 10 CD/DVD's a minute. There is no mess to clean up but it is fairly loud (about the same as a loud shredder). You wouldn't want to be talking on the phone while you were destroying CD's, neither would others in the cubicles around you.The one thing I'd like to see from Norazza is some real-life test results on the "destroyed" CD/DVD's. I wish Norazza would offer a $1,000 reward to a geek that could read data from a CD after one pass through the Data Destroyer just to see how good it really is. I tried reading a couple of the CD's after one pass through the Data Destroyer on both a Dell Desktop and a MacBook. Neither system could read the discs and both had problems, especially the MacBook, ejecting the CD because it was as though no CD was in the tray. I am hesitant to just throw the CD's in the trash (HIPAA ePHI) and ran them through a second pass just to be sure they were dead (and because it was kinda fun).

Not a high duty item. The first few hundred disks got messed up enough to render them hard to read. After about 500 disks, it took 2 passes to render them hard to read. Around the 800 disk mark, this machine was pretty much used up. It runs the disk between two metal rollers. As the sharp tips of the rollers wear down, this machine looses its ability to "mess up disks". The first disk I ran thru was really messed up, and my DVD reader couldn't read them. Several hundred disks later, it was clear that the dents this machine makes were very much less deep, and my DVD drive could read the disk just fine in one pass. It took more passes per disk to render them "hard to read". I would rate this machine at about 500 disks as a lifetime total.

jammed first time i used it-seller offered excellent return
