I just ordered one of these and am wondering about its longevity. I've done some research and from what I've read it seems that the torch type lighters don't last very long (2 years usually?). However, the Blazer Micro Torches seem to have a good record. So my question is if the z-plus is made in the same way as the micro torch--similar parts, design, etc, so we can get an idea of the longevity of a relatively new torch.
