It's not for the ultralight set, that's true. I've never seen one but I've been intrigued with them for awhile. It looks like a fast & efficient means of boiling water. The weight is not inconsiderable but if it serves as both stove and vessel it might be worth it.
Not that I'm exactly an ultralighter, but for day hikes I have put together a small but complete kit that weighs about 10 ounces including 2 oz of alcohol fuel. It's nice for soup or hot chocolate on a cold day.
Here are the contents:
1. Snow Peak 750 ml titanium pot
2. 2 fl oz capacity flip top squeeze bottle of alcohol
3. Bic lighter (standard size)
4. Swedish "fold-a-cup"
5. Titanium windscreen
6. Medicine measuring cup (for measuring out the alcohol)
7. Home-made pop can alcohol stove
As I say, the total weight is about 10oz, which is pretty light for a fairly complete set that includes everything except the water and whatever you're going to mix into the water. Well, I guess you could include a spoon for stirring, but a lot of the time I'll just roll up the package after I've emptied out the contents and use that for stirring.
