The aquagel "Gleitfreude" of Lumunu is a very pleasant gel. The sliding properties are very good without limitation. Nothing becomes sticky residue can be quite easy wiped off and rinsed / washed. Discoloration on textiles were not noticing. What I like: the gel has a pleasantly fresh but very, very subtle, restrained odor. There are no superimposed natural "scents". Even if times some gel accidentally gets into your mouth - what is indeed well happen ;-) - there is neither an irritating taste still too "geliges" mouthfeel. The bottle closure opens easily with one hand and is comfortable to use. The opening of the closure could be a little more closely, you would have to press a little careful, otherwise a good slug comes out of the bottle. But that's also just possibly desired and important so far no points deduction.
