I'm sorry I couldn't meet your expectations. I've adjusted the sound a few times, but as you said, the sound quality is uneven at the beginning. It gets better as you go through the middle. This lecture is more focused on understanding concepts, so if you're someone with some experience, you may find it lacking. For practical use, I recommend [Kubernetes Another Class]. If you can't get a refund for the lecture, please contact me at the email address in my profile and I'll send you a discount coupon for another lecture. Also, I'll add your comments to the lecture description and share them to help those who are considering this lecture in the future. Thank you.
