One star off because of the poor instructions.

, They give you tools to open your Mac GREAT, they give you a case to put your old SSD into to act as a super fast external drive FANTASTIC.Drive was easy to install and instructions easy to follow.

Just wished it worked and had better instructions and not assume everyone usees the same version of OSX.

The instructions were clear.

Once I found the right instructions for doing the format/restore in El Capitan, everything was pretty easy

Install went flawlessly, the instructions were mostly clear enough for someone with some image knowledge

The instructions on how to replace old drive were great, and this drive seems to be faster than the original drive .

The instructions in the video posted on this site were easy to follow (note: use Command-R to boot into recovery mode with OS X Yosemite)

Fast shipping and easy instructions.

Use the 9-5 mac and ifixit guide, as the instructions are worthless.

The package provides everything you need to replace the SSD, including the right screwdrivers to open up Macbook Air, and instructions

Easy, easy, except instructions for migrating data don't work.

This item was easy to install, everything needed was included and the instructions could not be any clearer...has only been installed for a couple of days but so far I am super impressed.

Transcend includes all the tools you need to remove the pentalobe screws from the back casing of the MBA (actually the most difficult part of this process since it's so easy to strip the screws) as well as instructions for removing the drive and tightening it back on

The instructions to option boot and choose 'clone' from the menu does not work with Mountain Lion.

All the parts and tools are there, the instructions are clear

the instructions were not good but the video on amazon was helpful, took me 5 minutes to install the drive, the case for me was useless as my original drive won't work, booted my mac to via Wifi, on boot up used the disk utility to format the drive, used the time machine backup from time capsule to restore, few hours later everything came back to where it was last week with 120 GB more capacity

Included instructions are incomplete.

The instructions are slightly oversimplified (specifically with regard to how you use the disk utility to copy the image from the old drive to the new drive), but that's about the only complaint I have

I decided to go with Transcend because of the positive reviews online and the ease of installation with clear instructions complete with video.

Troubleless installation, easy instructions

People seem pressed about the poor instructions, but I don't imagine it's really an issue if you've replaced a hard drive before

Of course the instructions weren't included in the box nor was there any information regarding the existence of the PDF file or the video

Included instructions are a joke.

Followed instructions, work perfect from the start.

Transcend's videos and brief instructions are excellent

No success following provided instructions

Easy instructions, tool kit was provided, easy to install.

Easy to install, though the instructions weren't exactly accurate/up-to-date
