Most folks in the world, including me, don't care about the latest tech and WOW factors. We just want a light that is cheap, and gives enough light for our purposes. The E01 does that for us, and although I carry a AAA light that has three levels, the E01 works for my wife and other women to carry in their purses. I have given several away and all were pleased.
So who cares whether it is the latest or not, as long as it serves our purposes. We each have the right to pay our money and take our choices. There is no way I would give over $50 for a flashlight. I have been satisfied with a Mag Lite using AA and C batteries, and a 6 volt lantern without a single complaint. It is nice to have one in my pocket when I get caught out after dark, but lights like the Thrunite Ti, iTP A3, and such that don't cost much, do the job for me.
I realize that most here on CPF are hobbyists, so go for it. There are advances and ideas that you have that in time improve the products. I am almost amazed at the advances since I lost interest several years ago. Keep it up, but realize you are the exceptions, and most of us do not place flashlights in a very high priority in our lives. But when I need advice re flashlights this is where I come.🙂
