In reply to gethin_allen: Hi gethin. From the written review:
Boiling time: 2.40 min (+ preheating 40 sec)
'Getting the stove to simmer was easily achieved by turning down the main control on the stove body, then tweaking with the control on the fuel source. The control offered means this is a stove that can do everything from boil in the bag to rustling up a full gourmet meal. I did, however, notice that at really low power the stove had a tendency to blow out when you removed a pan from the heat.'
