Lightweight set up, Piezo ignition works, and the stove has an awesome simmer levels. Stove goes from a full heat (very high BTU level) to a very low simmer. I own many different high end stoves and this by far is now my favorite. The only negative (very small one) is that to tighten the stove to a bottle, there is no where to grip it except at the Piezo igniter which is more fragile. I found that a very small lightweight allen key through the bottom vents does the trick. More than worth the price.
