Transparency is such a thing ...

The application of the gel is to use the same as for conventional foams / gels, but you have to look closely if you have everything well covered, because it is so transparent ...
The smell is not my cup of tea, but that's a matter of taste. As for the non-transparency, I had with conventional foams never problems when applying. Therefore I do not see the great benefit in a transparent foam. In the application, then interfere but that one has to look closely where you go was not (especially if it's done in the shower and his glasses did not). To overlook a strip happened to me not only with the first application.

Conclusion
Whether it is the enrichment of the market remains to be seen. It does what it says, is transparent. Otherwise I do not think it is useful. Therefore, only one star.
