A mobile phone with solar charging function, rugged and reasonably waterproof - that would have something for me and I needed a new phone too - but unfortunately it was quite a flop. The solar charging function did not work namely, the cell phone was hours in full sun, perfectly aligned, but has not the least bit loaded. Only the robustness can score a bit - is popped me twice properly to the floor and the spacey sleeve has its function fully met.
