I tried out a shark repellent, so you don’t have to. On the website, they didn’t provide a lot of information as to what these bands are made out of and why they work. They said they were scientifically proven, but I have not been able to find any type of data. Do you want me to keep trying with more species & more products? #sharkrepellent #sharkband #savesharks #greyreefshark #ocean #hawaii #diving | Kayleigh Nicole Grant
