Is Fahlo legit? Thinking about getting one!!

A friend of mines son showed me these fahlo animal tracking bracelets where he tracks sharks and penquins and it seems pretty cool!! Im a sea turtle and dolphin lover so I really like the idea that you can track a real animal with part of what you pay going to marine ecology, conservation and programs. BUT that said, I know there was some controversy on wether these comapanies really donate the proceeds and or trakc real animals. Soooo has anyone tried Fahlos tracking bracelets and is Fahlo legit?
