I would like to just briefly summarize and share briefly the things with which have been reported to me as a positive and negative.
Positives:
ease of use, multiple stages, pleasant material (not cold), relatively quiet, simple battery change
Negatives:
at the transition between the two colors (whatever "back" and "forward" may be called in the jargon, there is a small gap, and the material is different high -> depending on how one then applies the vibrator, this may at the skin to cause tangles.
Therefore, in my eyes 2 star deduction. 1 star for the imprecise fit of the composite parts / transition, 1 star for the corresponding price. If you already demanded so much, then everything needs to fit!
