Why  wouldn't you use it?

- It's got a double O ring housing, good to 70m - OK, you may not be going
to 70m but it's nice to have the safety margin regardless.
- It uses the same clone electronics that the majority of manufacturers use,
the major differentiator in quality being the lens - and Samsung have bought
in one from Schneider.
- It's got some excellent reviews.
- Where I come from, it's about 50% cheaper than the equivalent 'major name'
equipment.

Fair reasons to take a look?
