Thanks to Amazon for the quick delivery. Use this product for 2 days. The heat output is super. The radiator will warm very quickly and radiates shutdown still well off the residual heat. The 3 heat can be additionally regulated by a thermostat. Thus, the device switches itself on and off. The data is used for a space of 12 sqm corner and is only used by me in the evening in addition to about 600 watts / h. At full heating power 1500 Watt / h, a larger space would be to get good warm. Caution power consumption not ignore. Attaching the mount is simple. Depending on a strap like a horseshoe shaped, screw caps and two wing nuts is attached via one heating fin. Price performance is totally fine.
