Excellent customer service and very fast delivery time. We would definitely order from Herschel again. We bought a 500W XLS towel rail panel to replace a ‘traditional’ chrome towel rail, and used the existing wiring. We bought the battery powered controller, which works well and allows us to have a warm bathroom when we get up in the morning. Must mention that the heat generated is incredible (and very different) when compared to our old chrome towel rail in the same location (and half the wattage is being used too!)
