I bought the 128GB version of the JetDrive 360 in on 4th May 2015. I have been using it in my late 2014 MacBook Pro ever since, every day, many hours each day. I use this Mac all the time, and I use the JetDrive as a permanently mounted external drive for storage of projects I am working on as well as my iTunes library. It is usually around 80% full and has honestly proved to be 100% reliable. I have been using it through all of the macOS updates since May 2015 and also several pre-release versions of the OS (I am a developer). Now using it with Sierra 10.12.5.
I was looking into buying a 256GB version a moment ago and saw that many of the top reviews for the JetDrive said it has problems unmounting unexpectedly and/or "failing" early and so on. I have not experienced any such problems and just wanted to add my 5-star review for any of you wanting to buy this cute little device. It fits beautifully and is almost flush with the right edge of my MBP.
BTW, I always put my Mac into my shoulder bag with the JetDrive facing up, so that the weight of the Mac is not pressing on it. It may have nothing to do with anything, but I thought I would mention it anyway.
