Question: work in mac computers?
Document: I could not get this to work on my Sharp DVD Blue Ray player or my portable HP units. It did work on my HP desk top multi media computers. There was no way to find the &#34;Track 3&#34; that appears to be necessary to actually clean the unit, I could only hear the message.
When the DVD player in the BluRay began to have problems reading the DVDs, I ordered this and the first disc I tried it on was a revelation. The Player could not play the disc at all; after one cleaning with the Endust, the DVD disc plays like new. I now use it regularly both in computers and the BluRay machines.
The best money i spent, my Mac Pro DVD drive stopped reading CD, DVD, people tolled me that it was going to cost a lot of money to fix it.Thank God i found this just put it in and run on it track #3 and it will fix the problem.
It doesn't work, it made things worse for my 360. Don not waste your time with this product. It sucks.
Ultimately did not work for my Wii game console. Served no purpose other a waste of my time and money.
Item was sent just as described sent very fast and even though it didn't work for me it was still ok..
Unfortunately, my lens needed cleaning and this product did not work. I tried it several times, but it did not work.
even though people said they had used it to clean a WII I couldn't get it to work, so if that is why you are buying it DON'T
My sony quit recognizing my CD's. I was hoping this would work but it didn't. Unfortunately, player still doesn't work.
It worked great on everything we have, but apparently it doesn't work with some devices. Just make sure it works on whatever you want to use it on.
Answer: I tried this item on a tray loading dvd recorder/player and was not realy happy with the results. The lens cleaner is a cd that has a very small brush built in, therefore if you have a slot loading multy drive, I would'nt recomend because of the little brush having to enter into a very narrow area. There is a chance that it may damage your multy drive. This cd is more comvenient to use on a tray drive.
