However, the heater's heating coverage is limited to 150 sq. ft., which might not be sufficient for larger rooms.

Its black, rectangular design is simple and unobtrusive, blending well with most decor but does not offer much in terms of aesthetic appeal. Despite these drawbacks, it is a popular and reliable choice for those needing a quick, portable heating solution for small spaces.
