1. Its the type of ignitor that makes a small spark as opposed to a flint type.

2. I dont think there is a standard measurment of "wind resistance" so I guess you would have to ask the company that one.

3. Torch lighters are about the most wind resistant lighters on the market. Zippos are also pretty wind resistant but are pretty useless when the wind is blowing.

4. You need to bleed the air out of it. To do this- when it is empty take something and push down on the valve where you fill it and let all the air out.

5. See question #4.

You have three question 5's, but you should be able to get a good lighter for less than 75$, and yes Colibri makes very good lighters.
