Chtoocy 600W Large Dog House Heater

Excellent heater effective and efficient with nice hardware to attach to inside of shelter. I bought it for a stray cat that I was trying to help during the winter months and it worked excellent. It turns off when it reaches a certain temperature and turns back on whenever it needs to warm up to specified temperature which you program yourself. Easy to use. Excellent product. Sturdy. Solid. I bought an indoor outdoor water safe extension cord. You do not want to use just a regular extension cord with this. Also do not pinch or crimp extension cord make sure you have a hole to put it through from the indoor to the outdoor just to make sure you're safe.
