I used this for 4 hours a day for 3 months last winter for agave seedlings. It's in very good condition because I used it in an indoor greenhouse. I haven't moved it around, so there are no scratches. Perfect for greenhouses and the like! It's a 250W model with a thermostat! It automatically turns off when the set temperature is reached and turns on when the temperature drops. It saves energy and is very convenient because it manages the temperature automatically even if you leave it unattended! Highly recommended as it's getting colder! Feel free to comment if you have any questions! Will ship on Saturday. Thank you.
