Question: is it electric or manual
Document: I have probably have as many DVD's and CD's as the average media places. I have to stop lending them out because they would come back in such messed up condition, my wrists and hands would cramp from the manual repair devices.
They both had still one or two deep scratches left that probalby were the problem.I wouldn't buy this again but go for one of the cheap manual units. They are much faster and easier to use. I can clean a DVD just with some alcohol and I can add some car wax myself.
Now whether it is the library trying to salvage the DVD or other patrons, I don't know, but the pattern is very distinctive. I assume there are other machines like this out in the market and maybe they do a better job than my Aleratec. On mine, the buffing process essentially destroys the DVD.As a disc Cleaner, the Aleratec works well. But is it better than a manual cleaner or a clean, lint-free cloth? Only if you have sets with lots of DVDs.
After much homework, I decided to purchase the Aleratec 240131 disk repair kit. As recommeded in the owners manual, I progressively moved from cleaning, to light repair, to heavy repair. Although the DVD I was attempting to repair did not appear to be very scratched, it would not play on several DVD players. Once the disk was repaired using the heavy repair, I found it to play perfectly. I am very pleased with the Aleratec kit.
These were the only two DVD that couldn't be fixed with that cheap, easy and fast manual unit.The Aleratec system is kind didn't impress me and needs a lot of assembly to follow through the stesp. The cleaning unit is pretty worthless, nothing a littel Windex or alcohol and a paper towel couldn't do. The two buffing heads actually seemed to really take some plastic of the disc and the two repair heads did apply a wax layer on top. However, I didn't work in my case.
the product was pretty easy too use, I suggest that you read the instructions before attempting too use, the unit repaired my cd's after a couple of times of going through the cleaninf,repairing and buffing processes I like the unit mostly because of it being electric instead of battery operated.I would recomend it to most everyone.
I have had a "Disk Doctor" for several years and know the value of being able to repair and save my CD's and DVD's (games, movies, music and data). I never enjoyed the hand cranking required to use the "Disk Doctor" though, so when it broke, I was very happy to find the Altertec product. It has more capabilities (clean, repair and/or buff) and with the automatic controlled, electric motor power it is simply too cool. Love it.
you can easily fix damaged cds but you can't fix serverly scratched and scared up disc with scratchs in every direction from years of abuse. these disc fixers are great but you must use reason they can't  fix majorly damaged scratches but you can fix 99% of normal scratches and skips ect.
works like it is supposed to  it takes care of CDs  isn't that why we bought it, knowing you would hear about it if it didn't work
we got this to try and save some of our x box games it works on some but take a long time and many trys to get them going agane but in the end most of them started working it was quicker to bring to the move shop and have them run it through there mech. but good for a home if not to scratched.
Answer: It is electric
