The product did not come with the proper size lense ring adapter, even though the [...] product information stated it fit the panasonic GS-15. I had to contact the manufacturer (Panasonic) and get them to send me the 27.5 mm to 30mm adapter ring so I could get the camera to fit properly in the housing. After a three week period I received the proper lense ring adapoter and installed the camera in the housing. Thats when the lense ring holder inside the housing fell off. I used a bit of Gorilla Glue, [...] so far it has not come off through three filming sessions under water. I have noticed that the heat build up inside the housing can affect the performance of the camera after a short time recording underwater. I have had to minimize the amount of padding I apply to ensure the snug fit inside the housing. Also if the camera has a lcd screen that turns completely around you might want to do that so you can read from the screen through the clear rubber housing. That way you don't have to try and gaze through the smaller camera eye sight.T Adams
