Bought the 13/04 to 23h and delivered by AMAZON. Received today 17/04 => 4 days The article photo. I expected to silicone, a soft plastic ... I was surprised by the material is hard plastic, I hope that a fall will not break. I have not yet immersed, so I have not tested for leaks. Practice as mere handful to film, yellow is a little loud, but ... We will see in the water ....
