Clever idea, nice almost elegant design, well made but sadly but IMHO way overpriced for what's inside it and don't mention the cost of accesories such as a grill or kettle!
That said SWMBO does like me to phone home regulary when I'm away so keeping the cell-phone charged is a must, but I've got a cheap hand cranked flashlight capable of doing that because solar is rarely practical in darkest Wales!
Now if they made one that was a bit bigger, more chunky, capable of surviving bouncing around the back of landrover or getting dunked in a river and could charge 12-15volt kit such as PMR/ Amateur radio's, Sat Phones etc then it could have a wider appeal.
