BIFL and then maintain it for life

I am starting a YouTube channel with a friend based around the idea of items that can legitimately last you a lifetime. We will be doing a mixture of reviews and how to videos. The reviews will be assessing whether or not a particular item has the characteristics of a BIFL item and the how to videos will be about how to maintain the items that do have those characteristics.

All of that said are there any items you would like to see reviewed or instructional videos that you would actually care to see?
