Invent a new product and write about it to convince other to buy it

Invent a new product or service that I should go out and buy. Write at least 100 words to convince me (or anyone) that I should buy it from you. You get to make all of it up, so have fun!
Thinking about features vs. benefits, include at least one benefit of your product/service
Use logos, ethos, pathos, or a combination of them to persuade me. Use these in at least two specific ways (so if you only use one approach, do so in two ways. If you use two different ones, you could just use one for each.)
Identify which persuasive approach(es) you used and highlight or underline the text with the specific examples of each
