I love this product it is ultralight and easy to use but it needs a primer pan ( 玻璃樽汽水蓋/ 鋁罐底 + 5-7 drops alcohol, lit it and put under the stove ) to speedup the flame blooming. It creates nicely blue and quiet flame.
Legs are sturdy but not sure it holds in long-term.
30ml alcohol fuel can burn for 14 mins, the description that full load 44ml can burn ~20mins is pretty precise.
This video shows how a primer pan works.
