Though this is an amazing product and will help the unsafe water problem in the developing countries in particular. However, if you take a look at the discounted price that is $49, this becomes almost half of the average monthly income of a job holding person here in my country. The price will go up when this crowdfunding campaign is over and I don't know how this product being amazing can do any good to the end users? This is a question to the makers.
EPIC hunt!
