    Very happy! Good value NAS
    I had some extra hard drives and thought I’d purchase a NAS to put them to use. There was a warehouse deal on one. It said it would have visible damage, but to my surprise the unit is physically perfect, even though the box was mangled.The UI is great. Being a J model it doesn’t have btrfs nor can I install docker. But as a low-cost 4-bay NAS it works great to backup my computers (macbook with time machine included) and serve media through Plex. I’m not a fan of the form factor (drives aren’t accessible without unscrewing their back panel) but I don’t expect to be opening it very much.
