Not impressed. The cheap stiff plastic rubbish back was already broken when delivered in the box. I cannot believe that Calor would stoop so low with this cheap trash plastic back. Where are your safety standards? I have purchased Calor all my life. I have your Manhatten range which is strong and with a suitable metal SECURE back. This one is cheap stiff plastic junk and a danger as the model is slim built exposing the gas bottle and leaving it very insecure and liable to fallout. Furthermore, I was in the house. No doorbell rang. And it had been placed in and over the wall, sitting on the lawn. However, that said I do not think the delivery man broke it as the cheap plastic junk back was inside the heater and well packaged. Plus the package was secure and undamaged. This is just a pure simple case of brittle cheap junk by Calor that will easily break. Rubbish! Please send me a secure and SAFE metal back. This is rubbish and a danger. So angry with this junk. I am further not impressed with the on/off switch because it appears to be made of the same brittle junk plastic however, that said it works and there appears to be no problem with it. What were Calor thinking to produce this cheap junk brittle plastic UNSAFE back when the company has a historic reputation? I cannot believe how junky it is and more to the point how UNSAFE it is. Submit as Rita,.... of course, I will. I'll be emailing a complaint also and writing a review depending on your response.
