I have a Jetboil. The piezoelectric ignition failed within the first half dozen times I used the stove. Friends have had the same experience. Yet I see here on the forum people using stoves with piezoelectric ignitions.

I also have a Delta Windmill lighter with piezo ignition. It works OK -- up to about 7000' in elevation. Above 7500' or so, it's completely worthless.

QUESTION ONE: If you have a stove with piezo ignition, is that ignition reliable?

QUESTION TWO: If you have a lighter with piezo ignition, what problems if any have you encountered, and has your lighter's ignition worked reliably above 7000'?

As always, your thoughts and insights appreciated.
