We don't know about any in-box reviews for this F-16B (#K48159) from Kinetic.
tyuET-210 as depicted in the box art can not be made out of the box since it has the small horizontal stabiliser, kit has the larger version. So unfortunately some aftermarket is required to make a correct ET-210.
Some photographic evidence:

tyuOr modifying the kit ones is also a possibility.
