BUT: in the product description of the speech of 3 color filters. Unfortunately this is not true!
Included are only 2 (white and orange).
Unfortunately, the nice Amazon Support could not change the fact: Product has been returned in the first time and subsequently reappointed. Unfortunately, the filters were not still working. Too bad! Let's see if something is resupplied.
EDIT: At least 5 credit gabs in advance! Now that's good customer service! :)
