Had a similar looking style of toaster oven in the past, although I’m not sure if it was Oster or not. Either way, it had the exact same problem and was legitimately dangerous when the doors were open.

The doors were mechanically linked together so if you bumped a door by mistake then both would slam closed on your hand, hot metal and glass going into your skin. They also had to open 100% (which is rather wide, taking up a lot of space) or they would spring closed and, again, burn you.
