The heater's design is lightweight at just 7.29 pounds, making it easy to move from one room to another, which adds to its versatility. While the heater is efficient for its size, it may struggle to heat very large spaces beyond its intended capacity, especially in extremely cold conditions. Additionally, the fan can produce a slight noise, which might be noticeable, especially in quiet environments. Lastly, while it comes fully assembled, some users may prefer a unit with a more robust construction for long-term durability.
