drilled the warning sign today but suddenly found that the core showing in ebo site is not the same as they introduced the ball in youtube. i like the core of the signals therefore i drilled the warning sign, and now they use a different one?

come on ebo, how can you made that mistake?

Wow, that's interesting. I also saw the Warning Sign pictures showing the Signals core, which is basically the same shape as the Vital Sign core (but with different densities to give it different RG and Differential values). In fact, the actual image graphics made it look like the Vital Sign core, what with gray piece in the middle that wasn't appearing in the Signals graphics.

In any case, I also assumed that the Warning Sign used a variation of that core since the name "Sign" was in both the Vital Sign and Warning Sign.

I think you should contact Ebonite about this and see if they will do anything for you. I even want to say that their shelf pictures had the Signals/VS core images on it, so if you can find something with that image, you can state a better case that their materials were misleading.
