It will stain your desk!!!

Inside with this table top stand you get a piece of paper with this notice:

"If you place the stand inside your house [?!?], it may be advisable to put a non-sliding pad under the stand's rubber end caps/rubber inserts as they could leave marks on sensitive floors, for example parquet flooring".

I was 'careful' and placed it on a green cutting mat. Needless to say it left it's mark on it.

This specification should be the first thing in the product description...
