Fantastic housing for the G9 camera. The main feature is that you can hardwire the ikelite strobes into the camera (not working on fibre optics) which means you can get automatic exposure control from the strobe. The housing is quite bulky to compensate for the solid structure (keeping in only slightly negative in the water) which makes it a little painful for travel but if you are serious about your photography it's a hassle you will deal with. If i were to purchase again, I would prob get the dual arm housing for a bit more stability when using the video function on the G9 (not that it's amazing video). I've had one in the water for around 2 years now and with very little maintanence it's working like a dream.
