2.5''/9.5mm Universal Sata to Sata Optical Adapter Hard drive Caddy Bay CD/DVD-ROM 2nd HDD SSD Enclosure for Laptop with 9.5mm Dell, Optical SuperDriveTray Lenovo HP Acer Sony Apple MacBook Pro

Simplicity itself - just follow the instructions

One thing - not every original laptop bay faceplate fits equally well. Some will need hot glue to stop it from moving in/out and keeping it in that sweet spot, flawlessly connecting the edge of laptop and drive faceplate. Used it on 3 laptops, all faceplates sit differently.

Does its job well

Note that it doesn't come with a retaining latch even though one is described on the packaging. Fine if you're screwing the drive in anyway, not so useful if you were expecting a latch, were happy with your drive being minimally secured and wanted it to be quickly removable.

Totally suitable for the intended purpose.

The item I received didn't have the captive screws on the side but the small holes in the bottom you manually have to put in. The metal was also very thin, but for the price, it does the job.

Extremely easy to swap and increase your laptop memory.

The M.2 interface of my laptop motherboard was poorly designed, relying on a bridging flex ribbon that broke and couldn't be replaced. Also, the pin terminals were to close together and shallow for me to solder wires individually. Good thing that the laptop had an optical drive bay, into which I was able to fit this product to replace my M.2 SSD (which despite being six years old still has a few years left in it) with a 2.5 SSD instead. Saved me having to buy a brand new computer.
