Ebo-Jager is the industry standard for reliability.
Pro-Heat is a newcomer with an innovative design. I've always use Ebo-Jager but recently purchased a Pro-Heat Titanium to try it out.
So far I've had no trouble, but I've heard of others having it stay on. The controller is on the plug (convenient) and it will not melt or crack (nice).
If I were to recommend it would still be the Ebo-Jager but the Won Pro-heat has great potential.
If you wake up breathing CONGRATULATIONS!!! You get another chance to do it right.
