We purchased one in 2020 for a small bathroom. I had had a space heater in there previously but wanted something safer that took up less space. This heater ran pretty much non-stop during the fall/winter months of 2021 and 2022 (and on chilly summer nights as well). Just recently the toggle on/off switch stopped working. My husband wrote Econo-home to see if they could send us a replacement switch. Customer service person Ella said that if it was in warranty (3 years) she would send us a new one instead. We sent her the invoice and within a few days we had a new heater. Can't beat that for customer service! We like these so much that we purchased two more for the office and bedroom. They are energy efficient, and if you want a thermostat, you can purchase that separately. We just use the on/off toggle switch. They are 250 Watts, so don't throw off a blasting heat, but more gradually warm the space. Do they emit an odor when they are first used? Yes, but over time and depending upon use, this dissipates. If you have sensitivities to smells, you may want to use a different type of heater instead. However, we love these wall-mounted panels - they are great to supplement a small space in a safer manner than using a typical space heater. Heat is gradual, and works best when on for the better part of the day. It's not a replacement for your heating system, but great to take the chill off. We love them!
