In a word awesome! - these are some of the most sought after heads going but there was no way we would pay the going rates of $600+ for some of them sooooo this giftset although unofficial solves all.
Excellent build quality along with tight joints and attention to detail make them as good as the originals and a worthy addition to your G1 collection if you dont want to part with big bucks.
As with all KO's some will attempt to abuse them for a quick dollar so keep your wits about you when buying, you can see our spike comparison but the other main difference is none of the KO's has the copyright mark on them :)
As always good luck in collecting and thanks for checking out the pics.
