Hi Lucas,
I equipped my MacBook Pro (Retina, 15-inch, Mid 2015) with the Transcend Jetdrive 855 960GB. The migration worked wonderfully and I then installed the drive with the supplied tool. The tool is of high quality and fits perfectly. Since I had already installed an SSD before, I didn't notice a big difference in performance, but the machine runs perfectly. I cannot confirm Lukas' experiences (sleep crash, kernel panics). For me, the product was a great fit and has been running flawlessly since 30.8.2020.
Best regards
Nic

Hi Lucas, from experience: these discs may seem compatible, but they are not, or rather slow. Your Mac will have kernel panics, crash in sleep and shut down, and it won't be a great experience...
