The unit worked flawlessly on all 40 dives while using a Recsea housing for my Canon S95 housing.
Pros: Worked flawlessly, very even distribution of light, 3 levels of intensity of light for both wide beam and narrow beam, lasted multiple dives before needing rechaging with no diminishing of intensity of light as the battery drained over the course of multiple dives, charging took just several hours, great for night dives, seemed less affected by backscatter than other lights, and really penentrated much more so than many of the other hand held lights that I saw with the larger batteries.
Cons: Since I was both wreck diving and reef diving I decided to go with the option of dual white lights vs white and red. The intensity of the white light was too annoying for the fish and they tended to scatter them (especially for macro work). Having said that I was glad I had the dual whites for wreck diving. I don't like the portion of the ball head attachment that lets you attach it optionally to the flash shoe located on the top of my Recsea housing. You have to screw the unit to tighten it to keep it in place. Unfortunately as you adjust the light to redirect the beam this tended to loosen the light from the shoe. This could be a potential problem of loosing the light and not knowing it. I subsequently moved the light to the second ultralight arm and did not worry about it anymore.
NOTE: Soo many people had to play around with the little light when I was not looking that they did not know how to turn the thing off (you have to push the switch in either direction for a couple of seconds). So I found myself having to go and turn it off for them. They all seemed pretty facinated by it.
NOTE: make sure when you order the unit that if you are using it for uw photography that you get the ball head that is compatible with the ultralight setup (if that is what you have). Mine came with the hand strap that you see many divers using these days. The shop had to send me out the optional ball head so I could mount it to my ultra light arms.
If I purchase a second light to help with the video portion of lighting then I will more than likely get the white/red light combo to help with macro shots by using the red light.
