1. While focusing on initial use is good, it's too basic. In practice, the usage is so fundamental that it's almost meaningless. It's at a level where you might wonder, "Are they telling me to learn this and apply it to a project? I'd get scolded!" In reality, breaking it down, there's more content on the characteristics of caching + how to use and deploy with AWS than there is on Redis itself. If it's a Redis course, the main focus should be on Redis content. With a name like "Redis Introduction/Practical," a title like "Optimization through Deployment and Caching (with Redis)" would be more appropriate. 2. The price is too steep. If the instructor were explaining difficult and extensive content with their expertise, the price would be reasonable. However, for content that is so basic (disappointingly so), this price is too harsh. 3. It would be good to have additional learning materials, even if not used in the lecture. It would be great to have content that allows for further learning, even if it's not directly used in the lecture. For example, instead of saying, "We only need to know this," it would be better to say, "We're using just this for now because we're in a hurry, but you actually need to know this, this, and this."
