Thank you for viewing! Film heater for hamsters and hedgehogs. Simply place it under the cage, making it easy and safe. - Power: 100V / 45W - Size: Main unit W120 x D170 x H10 (Film part 1mm) Power cord: 1.85m Power on and operation confirmed. Essential for the coming cold season. With automatic temperature control function. Used 2-3 times after purchase, but I moved to a warm room, so I haven't used it since. Box included, instruction manual included. Thank you.
