The Good:- Compact, lightweight, and highly portable.- Excellent for backing up Mac and iPhone files with reliable HD performance.The Bad:- Lacks a pass-through USB-C port, so you can��t charge your device while backing up. If your iPhone or MacBook Air runs out of battery mid-process, you��re stuck.- The lanyard hole design is flawed��impossible to attach the line, it can��t exit, making it essentially unusable.- No companion software provided by the manufacturer to manage or automate backups, which limits convenience.
