I agree that there needs to be a balance and furthermore, that finding that right balance is very difficult. Probably why marketing whizzes get paid the big bucks.

In your example though, there is difference in that you're an actual person representing a reputable company on-site, not a random anyone-could-have-created-this advertisement on the anonymous web. From more trusted sources, I'd be interested in hearing the benefits and not necessarily the features. But in an environment where seemingly every third website activates my anti-virus software and I read about data hacks every week, I definitely don't trust Internet ads filled with hyperbole and exclamation points.

It's true that people in a usability test don't behave exactly the same as at home, but that actually proves my point. If they're obviously trying to be positive and helpful (no matter how much you tell them to relax and be honest) because they're constantly saying nice things about the site or app, then it's even more noteworthy to hear any negative comments or see that they're confused. Especially in the beginning of the session when their energy is higher.
