i must admit that the landrover s1 phone i have is a1 for bushcraft ( i know i am a little biased and not trying to justfiy paying the 250 notes to get it sim free), but i generally put my phones through the paces at work (middle of the west african jungle), and so far it has faired me very very well (has lasted 3 times as long as normal phones... and yes i will take sonim up on there 3 year warrenty if it does break)
i dont have to charge it up for 2 weeks at a time, and when i do an hour with my pocket solar charger gives me another week or 2..... the led torch is fantastic and having the gps on it is a life saver (litterally...... trying to remember where you parked the truck in the jungle at night can be amusing..... i find it isnt.)
the fact that it ip67 rated has also proved really well .......so far got the phone very very wet in a river crossing and the down pours here, have has it ran over by a 40 tonne truck, it has survived the 40 deg C whether and 95% humidity, is generally abused..... all this and it doesnt skip a beat
so personally if this phone can last over a year in the conditions i put it through it will be a walk in the park for the UK!!!
