Your advertising tone sounded genuine to my ears. There were times where it sounded like you may have been going a bit too fast. But that bit with all the disclaimers was hilariously spot on! Nice improv at the end, too. Good job! :)

The first part is great! very easy to understand. the second part is a bit too fast.

Nice job! I think you could benefit from slowing down by quite a bit, simply to focus on your articulation. While you did a good job keeping up with the quick pace, having a higher level of clarity and a clear voice in general is more important from a voice-over perspective. Nevertheless, I was honestly impressed with it! From there, I would recommend working on increasing your energy and passion; I want to TRULY feel like you are selling this product with everything you have! Or something along those lines anyway. Well done!
