We purchased this silicone heater for our industrial needs and it has been a top performer. The heater delivers consistent and reliable heat for our drums and pails. The wattage on this heater is perfect for our requirements and has the added bonus of being easy to install. The high-quality silicone material is durable and long-lasting. Based on our own experience, this heater is a must-have for any industrial or scientific setting. The only con we can think of is that it may not be suitable for smaller or non-metallic containers. Overall, we highly recommend this product to anyone searching for a dependable and efficient method for drum heating.
