I think it depends to a certain extent on how a person takes care of their equipment. If you're someone who is mindful of how you handle your equipment, I'm willing to bet it will last at least until you're in a position to get a provari. If it last any longer, you'll have a nice backup
device.

That's all you really need it to do correct? The manufacturing? Meh, it's on par with the cost and the cost balances out the equation...besides, I don't see it failing any sooner that any of the other plethora of mass produced pv's out there...Lava Tube, zmax,etc.
