Do VSLs really work better for Native?

[megs]

Do they really work better than a text landing page? I was looking at the the full funnel before promoting Kerassentials and the drop off rate has to be massive if you have to sit through a 25min toe fungus video before the option to purchase the product is even there. I guess the CR% of those that do finish it is very high.

Has anyone done any A/B testing? I'll do so eventually (and report back with the data) but my campaigns are far from stable right now and don't wan't to throw to many variables
