Familiarity: I've used it several times
I have had some difficulty with the igniter but overall the unit works fine. This unit is almost strictly for heating up water and other liquids. It is somewhat useless when it comes to cooking things. Unless you like burnt and unheated food. This can completely get rid of a cook set if you are looking at switching to Freezer Bag Food.
That being said it does the job of boiling water incredibly quickly, almost too quickly.
