Installed in my mid 2012 MacBook Air. The upgrade was simple, anyone who can use a screwdriver can perform it themselves. The drive works perfect in my system, sped the OS start-up time significantly. Have no cons about the product.

Hate to write negative reviewers especially for a product that has received so many good reviews and I spent so much time "researching" before buying. Seemed best out there and 5 year warranty. Installed as internal SSD in my MBA.

I've only just installed this so can't comment on any long term issues. But the price was OK, the delivery typically fast with prime, the instructions on how to install it and clone your existing drive detailed and installation was straightforward.

Almost two weeks into installation and the drive is working fine, the other reviews were accurate and helpful. I do notice a very slight dip in SSD speed but the very massive increase in space is worth it for me.
