content: I bought this adapter to recover the files from my girlfriend's dying laptop hard drive. I had used similar models in the past, but the Sabrent stood out with its additional power supply input for 2.5" models.Installation was easy enough: unpack and plug things in to the right places. 2.5" drives plug in directly. I plugged it in to my Linux machine and it worked out of the box; same with my Windows and Mac machines. Turns out it was a good thing I got the additional power input: the laptop drive I needed to recover required more power than was provided by just the USB adapter to run correctly.All in all, a solid product that works as advertised.
