Yes, I've built several of them, along with other designs.

My personal take: this guy has a persuasive way of describing and presenting his (pet) stove -- he makes it sound as though it is very unusual, and has some real advantages over the others. He builds it up. He doesn't evaluate it in a very balanced way.

Some of the other alcohol stoves are (1) easier to make, or much easier to make, (2) easier to light, (3) less likely to have problems during use, (4) comparable in efficiency, (5) more reliable, (6) more consistent, and (7) comparable or better in heat output. -- among other things.

The pictures of the jetting flames are cool, but so are other types of flames. I found some of the others to work better.

I prefer other stoves.

Preferences vary from individual to individual, though -- you might love this stove. It might be your personal favorite, so by all means enjoy it if it is. I suggest trying out some of the other ones, if you are inclined to do so.

www.zenstoves.net has many good designs and links.
