But I don't have an alternative. The whisperlite I have is about 20 years old. It looks the same but maybe they have improved the design. It can be difficult to light and get to temperature. I have eaten a few cold meals because I couldn't get it lit. If you use it a lot then maybe you can figure out the fine points. It is very light, which is why I bought it. But if I were going to go somewhere where I really needed it I would probably go shopping for something else.
