One can from the picture her not realize that ONLY the gray webs are made of silicone - the violet surface is hard plastic - a fact that is not mentioned by the provider.
Personally, I would have had in mind pure silicone, but used the pedestal is of course fully for the purpose - because there is nothing to complain about. That is why only one star deduction - vll streamlined the provider yes out to be more specific. ;)
Big plus: on a flat surface is the part also wonderful plan, and does not wobble!
The round hole in the middle way, is actually one thing not necessarily be seen from the figure ...
Conclusion: if you do not insist on pure silicone and knows in advance how the nature of the material is, there really is no reason for a non-recommendation.
