Solo Storm - had it for a year. Went camping with it but didn't realize I was almost empty and the result was a very low flame. Mind you I was using cheap Ronson butane which caused inconsistent burning. After I refilled with better quality butane and fine tuned the burner for my elevation (1900') she works like a charm. (Hey, I didn't know you have to fine tune the light for elevations - part of the reason why I had a smaller flame at 6000'.

I've not had a problem at all with the seal in simple damp weather but I haven't encounted a true dunking of the lighter yet.

The hotter more intense flame is more useful than a Bic for melting or igniting items, IMHO.
