ACT Commercial
"cleans gums and kills mouth bacteria" This is a good example of a water is wet claim. There are other brands in the mouthwash category, such as Listerine, which claim to and do the same things.
"helps prevent cavities" and "promotes healthy gums." this is an example of weasel words propaganda with the usage of helps and promotes.
There is use of a testimonial in this commercial using celebrity Christie Brinkley. She is used to further another propaganda device, the Hidden Fears technique. Towards the end of the commercial, Christie asks consumers whether or not they are taking the best care of their smiles, and suggests that shouldn't they be taking the best care of their smiles, as she flashes her pearly whites across the television.

Geico Commercial
the claim "so easy a caveman could do it" appeared numerous times during the commercial; on billboards, on street signs, as a spoken sentence. This idea is being used to appeal to the strivers who want directness in their commercials.
This strategy works because it uses the plain folks appeal; talking down to the masses so as to seem like them. Many consumers like being able to see that the ad has made an attempt to make them feel as though they can obtain the product without any complications, and that they will be successful.
"15 minutes could save you 15% or more on car insurance."
