Baader TurboFilm?

[Alfian]

I came across this, more by accident than design and wondered if anybody uses it.

I cannot find anything much in terms of peoples experience of using it. Does it live up to its claims in terms of optical transparency? Is it easy to use? What are the negatives? On a reflector I imagine the cool down will be affected. Dewing?

Only review I can find is this one and it seemed to show very little image degradation. http://www.broughastronomy.co.uk/apps/photos/photo?photoid=121780140

I might it need to consider this when I get a telescope as I do most of my observation near the beach.

Edit: I've just purchased some so I will give a review in the near future.
