When I tried this product I was amazed at how efficient it was at controlling the temperature in my work environment. The Quima Thermostatic Adjustable Temperature Hibernation is an Industrial and Scientific marvel that allowed me to choose the right temperature for my work conditions. The pros of this power tool are its user-friendly design and the fact that it's built to last. However, the only con I noticed was its relatively high price, but I believe its worth every penny for its functionality. Overall, a superb PURCHASE for any industrial worker! .
