OK for general use

I bought this pack about an year ago with my Sony DCR-DVD 108 purchase. It was recommended by Amazon with this camcorder. The DVD disks are good for their intended use. The quality of video recorded is very good for first 3-4 uses and then slowly goes down with multiple rewrites.

Per my experience, I will recommend to reduce the number of formats. I only format once it is completely fiished with 30 minute recording. Multiple format will result in deterioration of the video quality.

Also, handle them with care. Scratches etc can damage them permanently as with all CDs/DVDs.

Incompatible

Make sure you know that these will work with your camcorder before buying. Apparently, they work fine with Sony camcorders (the packet too says so) but not with Canon. Also, it's incompatible with my new Panasonic camcorder too. Interestingly, it was displayed as a combo offer when I bought my Panasonic camcorder, which is the reason why I bought it anyway, but got duped.

Not rewritable in Sony Handycam

As others have said and anyone can see, these are very inexpensive rewritable mini-dvds. They may be rewritable when using them to hold data in a computer but not in my Sony Handycam.

After using a disk in the Handycam, before the disk can be played in a simple dvd player the disk must be finalized in the camera. Using another brand of mini-dvds (JVC, much more expensive) the disks can later be rewritten or added to by telling the camera to "un-finalize" the disk. Using these Memorex disks the images are retained well enough but my Handycam cannot "un-finalize" the disks for rewriting. I can reuse the disk by reformatting but that, of course, necessitates deleting the information already on the disk.

So I give these three stars. On the plus side are the price and the fact that, like most rewritables, you can reformat them or delete the most recently shot image on the disk; but on the negative side is that they can't easily be reopened after finalizing to add new images.
