Just as a bit of backing for Lambchops here.
I bought one of the first wave of RC SureStarts to ship and use it
every single time I start my RB from cold. I have never suffered from any kind of overheat (300f, you gotta be joking surely!!) and have never suffered from a blown bulb, in fact I dont recall anyone ever having mentioned a blown bulb on the MB forums.
What we have here is something that is like all the very best idea's. Its simple and easy to use, and pretty much everyone smacks their forehead and mutters "why didnt I think of that??". Yes you can use a hair dryer, or fab up your own copy, but the RC Sure Start does exactly what it claims to do, with minimal expense and minimal fuss.
