From the PixelRocket team:

We are raising money this year for Charity:Water, a favorite organization of ours that is on a truly huge mission in bringing clean water to the world.

For EVERY REVIEW we receive we will give a gift of $100 in your name to the campaign, and if you feel so led we invite you to share with your friends and colleagues to help provide more clean water to the world.

100% of the money will be used to build clean water projects, and when they’re complete, charity: water will send us photos and GPS coordinates so we can see the exact community we helped.

From Charity:Water:

Many of us have no idea what it's like to be thirsty. We have plenty of water to drink -- even the water in our toilets is clean!

But many people around the world don’t have that luxury. Every day, about 1,400 children die from diseases caused by unsafe water and poor sanitation. But it doesn’t have to be that way. There are simple solutions like drilled wells, spring protections and BioSand filters that help provide clean water to communities around the world.
