I got me, the Super Slim ordered as a replacement for my big old PS3 with 12GB and wanted to use my old hard drive into this further. So far so good, but you need to buy this mount, the old does not fit due to the changed console design. In itself not a big problem, but 10 for a bit of metal with a few screws, but something much.
There is not much to say to itself, it does what it should and with no problems.
