I bought the machine April 21, 2012, first use a few days later in 1.m water, already shows signs of weakness, can not make it work, so I followed the instructions to the letter. returns to fonctionnement.Ne me tightens again in August 2012 and after two uses is totally HS !!! a bit expensive as purchasing for so little use and more I find that the photos are not extraordinary, focus far too slow to take pictures underwater. While I have never used this kind of product, I always work with SLR.
