Note:
I'm sure your hunt is undervalued and it's right to get help to crawl up to the better ranking (at least to TOP 100). Why ?, because i think it's "COOL".

This is interesting hunt @arianna22

What i most like from this device is :

Besides being solar powered, the W100 can be used under water. So, adoption for this tool can be used by anyone. I see there are pictures of fishermen who use it, and this is very useful. Free enery, and multifunction devices.
