Response from
Hi Steph,

Thanks for sharing your wonderful feedback with us and the community. 

Yes, you are absolutely right on average we spend $500 per year on the bottled water, which has a huge impact on our economy and the environment. 

CrazyCap costs less than 0.001 per gallon of treated water providing up to 8 million ounces of drinking water. 

If there is anything else we can do to help, please let us know.
