New fixative for pastel worth trying?

Hi to all you pastel lovers; In Holland Clairefontaine is advertising with a new fixative called Revolution. It should be safe, not changing the colors, more the effect of "freezing"the work,
Has anyone used this already and how well is it liked?

I’ve not heard of it here in California. How do you like it?

Waiting for somebody else to try it, not excited about using fixative of any kind, so I wonder if this would be a good product, Greetings, Albertine

AZHolland, I have not used this particular brand of fixative. I will have to try to find it and try some on my pastels.
