The Jetboil Sol is, in my opinion, probably the best ultralight weight backpacking stove money can buy. I have used it several times now for overnight backpacking trips in conjunction with dehydrated meals and 3in1 sachets of coffee with great results. It is well thought out, weighs in at under 600g including gas and boils enough water for a dehydrated meal and warm cuppa in under two minutes.
The only thing I can fault it on is the piezo igniter which can be a bit hit and miss.
I am yet to find something that can do the same job within the same weight and size category so it's 5 out of 5 from me!
