I love it. Small streamlined canister, very nice design details, nice white light beam, a well protected bulb, good customer support. Since Terkel is a friend, I expect no less, but I still highly recommend them.
I find canister lights much easier to use, less awkward and bulky, and they make diving alot more fun. Like some others here, I dive in the Pacific Northwest, where vis tends to suck, so lights are vitally important for communication and safety as well as just being able to see cool stuff.
Even in water that is clear as a bell, though, I love using my light. Everything looks so pretty.
I think HID canister lights are becoming increasingly popular in recreational diving and are a great way to go.
When I look at critters now I try to keep them in the periphery of the light and not shine it right in their eyes, in case it does bother them.
On night dives, toward the end of the dive, when we're not looking at stuff, just doing stops, I like to turn my primary off and use my Scout to signal if necessary. That way I can play with the bioluminescence. It's also fun to watch other divers' lights at night from a distance; it's like a light show. And night dives for me are incredibly relaxing. Basking in the ambient glow while doing deco stops is just pure fun.
We stay in each other's line of sight when our lights are off, of course.
Hrmmmph.
