After I've still decided with my getting on in years Macbook Late2008 to install an SSD, I ordered this Caddy, to continue using the old hard drive can. I was not disappointed. Use the installation instructions from iFixit the exchange with the SuperDrive worked great! Everything worked immediately. I'm very satisfied.
One small thing I noticed, however, is not even worth a star deduction: the Caddy zerkratz very easily. At the slightest contact with other materials (during installation) you plan scratches. Well, but the beautiful view it is anyway not intended - of the forth, everything was perfect!
