The strobe is okay ( it works) but like any camera underwater a add on stobe would make a big inprovement. Just plug it into the USB with the supplied cable, turn on the camera, selecty PC from the camera viewer and down load like any storage device. I did not use the software that came with it, I have enough stuff on my desk top now. Of course like any new toy play with it before you go diving as you have to scroll through options to change things, a pain in the but if your trying to learn this underwater. It stayed water tight, as long as you take the time to close the door properly and latch it I dont see were a flooding issue could happen. Before I left I ran a peice of stainless steel braided cable through the hole in the camera and use a crimp to secrure it. The strap they send is the same one as the mini, a peice of junk. I had not failures except due to me, not the camrera. I did lose a set of pictures at that depth due my stupidy with my laptop at the time but have 3 short videos and pics form 5ft to 20 ft.

I was only able to make it to one 50ft dive but the camera hend up fine. Well the camera and I made it back in one peice and I will be posting some pics in the next couple days.
