The pricing and delivery were very good and the item was as advertised, the to stars however were because the gas heaater was sold at a time when calor were not allowing suppiers to sell new gas cyclinders to customers. If you didnt already have a used cyclinder you could not buy one which means you cant use the heater....there was no warning when selling the heater or advice that you need to already have a cyclinder, so clearly extremely poor selling heaters that they then stop you from using. Amazing. Thankfully and by oure chance, within a week, calor have now lifted the ban if new sales, but that was chance. So, 2 stars for service and lack of amy customer respect for Calor Appliances as a company. Product is fine.
