I've been researching various single-function microwave ovens lately, and I still feel that the simplest ones are the easiest to use. Products specialized for heating are surprisingly abundant, with many options from well-known brands like Sharp, Toshiba, and Panasonic.

Personally, I'm interested in the Sharp RE-TD184. Its flat interior makes cleaning easy, and it features a 1000W high power output along with an absolute humidity sensor, which likely results in more even heating. For single-person households, the capacity is just right. Also, Panasonic's NE-FL222 seems to have quite accurate automatic modes, and the one-touch door opening design looks quite convenient.

Toshiba Lifestyle's ER-S10A feels more like a family model, with a large 23L capacity. Its consistent heating performance in both manual and automatic modes is a major selling point. On a tighter budget, Toshiba's ER-NS170A or Twinbird's entry-level models offer good cost performance, and for simple operation, they are sufficient.

When choosing a single-function microwave oven, the most important factor is how evenly it can heat without uneven spots. Therefore, I think opting for a sensor-equipped model, even if it's a simple microwave, is less likely to lead to mistakes.
