Humor is one of the best strategy to infuse interest and grasp attention because almost everyone can relate easily to. Although it may cause distraction to fully sell on the qualities of the actual product.

In the first 5s (crucial period to grab attention), it has successfully managed to capture the viewers' attention and create suspense. It starts when two different subjects of contrast are placed into the environment where the usual reaction to the situation is different from expected. The situation starts in the shore where a nerd and 3 babes who seemingly intend to tease the guy.

Then the suspense is held when the girls teased him by removing their bottom suits and waving it in the air (quite suspected not much of a shock).

Next, we as audience will think so 'how will the guy react?' This maintains the audience. Next, he walks closer towards them with a perverted look and ...

starts to take snapshots underwater using a waterproof camera!

After this, it zooms in to the expression of both sides and the nerd lifting up the camera and looking into it.Then the product is introduced, however, there is no description about the text besides the use of audio which should be improved further with use of typography.

Later, there is reinforcement of info on the clarity of product as one quality to conclude it showing the guy relaxing and looking at the photos he has taken(with a shy expression).

Also, notice how the clear the water is! and the ladies are represented like "charlies' angels" with different skin tones, and the representation of a nerd as a white american.The way the nerd speaks also clearly confirms his character, but later the move that he makes starts to contradict what soft-spoken nerds would do!
This ad. is overall successfully with its catchy video but it has relied on making us change our perception of different people (stereotyping),e.g, nerds & babes.
