yeah with the amount you save you could buy a pretty good fire extinguisher and fire insurance...
*trollface*
But yeah... I dunno. Never tried them. I know the first ones went on fire, but they fixed that plastic clip nonsense. They still don't have the best rep for reliability, but i don't think they'll set your house on fire any more. Supposedly they sound pretty good for the money, it's just the reliability that's the problem. :?
