I think its the small volume that makes it worth it (faster to heat up, efficient) so I can see why people would buy one.
I personally don’t have one because I don’t exactly value my time. I throw my food in the cold oven and set it to whatever and check back later. I don’t have any motivation what so ever to care about pre heating or having my food ready 10 minutes earlier.












My server got hacked once and was mining crypto! I noticed it when I heard the fans were at 100% when walking passed the room lol. Turns out, qbittorrent-nox used UPNP for its web admin endpoint enabled by default and qbittorrent can do many things like run custom scripts. My mistake was not changing its login credentials. Exposed my full system. Live and learn.
