I just received and tried a burner from iwalker in China bought from Aliexpress . It burns quite well in my old Optimus 155 and function better than previous burners I had received from UK which had many mechanical problems, some total scrap. It also preheats faster than the Hansa burner. Link to product below IWALKER Paraffin Stove, Diesel Stove Valve, Silent Cap, Outdoor Camping Stove Burner, European Specifications, M14.6 * 0.75
