Under the Tank Heater, 6x11

The Ultratherm Under the Tank Heater, measuring 11 x 6 inches, presents a mixed bag of user experiences. On one hand, many users appreciate its effectiveness in heating and recommend pairing it with a thermometer to ensure the temperature is adequately maintained. This emphasizes the importance of temperature monitoring for successful usage, highlighting that while the heater is reliable, optimal performance relies heavily on user diligence. However, the product has received criticism for certain shortcomings. A notable review indicates that a customer experienced a failure after several years of use, which raised serious concerns given the risk of their hedgehog attempting to hibernate—a life-threatening situation. This incident, coupled with inadequate customer service from the seller of the product, has led some to question the overall reliability of the Ultratherm heater. Additionally, feedback suggests that the heat output is not focused effectively towards the tank and that supplementary insulation and heat-resistant tape are necessary to improve performance, as these items are not included with the heater. Overall, while the Ultratherm Under the Tank Heater serves its primary function well for many users, potential buyers should be aware of its limitations and the need for additional accessories to enhance its effectiveness. **
