The animations look great and are really well done, but if you think that it is purely a drag and drop action to cusomize the lower thirds you are heavily mistaken!
Almost every lower third is built exactly around the dummy name in the preview and if you are using a real name that is even one or two letters longer, the whole setup doesn't work anymore and you need to do some seriously advanced tweaking to get them working for your personal needs.
That is of course not just a problem with this lower thirds pack, but with every pack that is out there as far as the comments are right.
Still, it would be so much easier if the dummy names that were used were at least a bit longer in general, to better fit real world names, because seriously, who has a name that is as short as "john doe"???!!!!
Anyway, if you know your way around After Effects, you will still get a great benefit from this pack, but if you are an unexperienced user, you will definitely not be happy with this product, neither wit ANY of the titel/lower third packs.
