Customers generally find the product easy to install and appreciate its functionality for warming up spaces quickly. The performance is noted as good, with some units lasting for many years. However, there are concerns regarding temperature control, as some users report a lack of a visible thermostat or the unit operating only on an on/off setting. Durability is also a point of contention, with some reviews indicating the product stopped working after a short period or that components are made of cheap plastic.
