You get what you pay for. It does well with room temp and cold foods but I would not attempt heating up food in it, especially liquid foods. I tried heating up soup in it (my mistake) and the container got deformed from the hot liquid. Luckily, i had the container in a larger bowl, in case liquid spilled out, and I believe that's what kept the plastic container from caving in and completely going flat. The plastic container did go back to its normal figure after the soup cooled down... but it was def a learning lesson.
