This dual functionality allows it to serve as both a heater and a fan, making it useful year-round. The heating capacity is substantial, with ceramic plates that heat up quickly, ensuring you stay warm even in cold weather. The maximum temperature setting is 99 degrees Fahrenheit, more than sufficient for a small bathroom.

Portability is also a strong suit, as the unit is lightweight at 5.91 pounds and can be moved easily from one room to another.

However, the price point might be a bit steep for some, and its size may not be ideal for very cramped bathrooms. It also requires batteries for the remote, which is an additional expense.
