Even if the case has already endured a lot of salt water, I'm still before each underwater adventure nervous if the seal does what it should. But no problem! Well lubricated with silicone paste photography is a fantastic experience underwater. I can as an avowed Warmwasserfan the buttons operate very well with his bare hands. As the wearing gloves is I can not say unfortunately. Something I feel inconvenient placement of weights and that you have to buy them separately. I recommend here the regular Check if the screws are still firmly on the weights. A loss would be OFF, which must be clearly stated. The lift is very large, and even while snorkelling the housing without weights is useless. A lint-free cloth (lens cleaning cloth) should be always available, to remove any dust particles off the lens.
