+2 on the windscreen. I had one given to me that was custom made out of an aluminum beer bottle. Worked very well. I took it winter camping, and that was a pain. This design had a fiberglass braid around the bottom so you could 1) handle it when it was lit and 2) you put more alcohol on the outside to heat it up quicker.

The steps to light it was:
1) Put alcohol in the center
2) Put alcohol on the braid
3) Light the center
4) Light the braid

Worked very nicely. The only "difficulty" I've had with them is finding something to store the fuel in that doesn't scream "DRINK ME". I've been told that stuff will blind you faster than... I dunno, just don't ever drink the stuff. Finally found some shampoo bottles at Wal-Mart that worked. They had a screw top for filling, and a flip-top for pouring.
