Not much to review since it's just a disk but I use these to transfer files from my 20 year old laptop to my 10 year old desktop without the hassle of needing to burn CDs or try using it over a network. It does what it needs to well and so far I've not had any problems with the drives or disks.
These Zipdisks worked great with the only complaint being that they were not wiped and had someone’s previous personal data on them. I was able to wipe them with no problem so it wasn’t an issue.
