Yes, i have many of them, the most louzy ones i find the Kings one, i found the level not deep. I learn more in depth with the oxford serie, it's spoken and here and there some animation, but much better for your theoretical knowledge.
I have some Jeppesen PPL serie, and the Jeppesen IR serie and i find them much better than the kings ones.
I guess that the sportys series are the best in video viewing, get the oxford serie for more in depth training
cheers
