i bought this because i love taking pictures. we are going to aquatica this summer and i need something to protect my phone on the water. i have tried the necklace phone protector before but it didnt work for me. lucky i found this this is perfect. i have try this and put it napkin inside and submerge into the water and its really is waterproof. its very comfortable to wear and it fit me perfectly. the adjustable strap is good quality and this would be perfect to bring.
