**** The Comfort Zone 3,600W Electric Hard-Wired Portable Industrial Heater has garnered mixed reviews from users, highlighting both its effective heating capabilities and concerning quality issues. While many users praise the heater for its ability to warm large spaces efficiently, especially in extremely cold conditions, the product's reliability has come under fire. Several customers reported significant issues with the temperature control knobs, with multiple failures leading to frustration and dissatisfaction. Additionally, a handful of users experienced safety concerns with the thermostat, with alarming reports of burning smells and potential hazards resulting from malfunctioning components. Despite its initial effectiveness, the experience of heating output declining after a few months has been a common theme, leading some to describe the heater as soon to be worthless.

Ultimately, while the Comfort Zone heater has the potential to be an excellent choice for industrial or garage spaces, potential buyers should be aware of the quality control issues that could affect the durability and safety of the product. **
