Good information. I was going to recommend that you have links to every product that you talk about, or show in your video, but I see that you do have links to articles which have this information. I would still recommend having a quick summary of the products shown. I am very well versed in this subject, and I actually have many of the items shown. However, the “key” that was shown that enables you to open up water sources, I do not have. I had heard of it, but had forgotten about it. Now, I want to get one… but it seems that I have to dig through all the articles and links, etc., to find it. If you had a summary, I could bypass the things I already know about, or own, and get right to what I need. Otherwise… great job! I’m looking forward to the rest of the course.
