Surely neon screwdrivers serve a different purpose to "two probe testers" or light bulbs. For example, what if there's a break in the neutral?
Your neon will still tell you the live is live. I always test a neon screwdriver immediately before relying on it, and I have a cheap non-contact tester as well, but I wouldn't trust the non-contact device with my life.
Thanks. I accept all that, but most of my experience has been with existing wiring, when I have no idea whether it's been installed properly, or if standard colour codes have been observed. My point was that using a two probe test, or a lamp, only tells you anything if you are referring to a known good ground or neutral, whereas the neon screwdriver(if it's working properly) tells you what could happen to you.If you're following safe isolation procedures, you would surely be testing at the source of the circuit, then locking out prior to working anywhere else; finding out if there was a break is then a case of running continuity tests on the individual conductors, (or by looping LN, NE, LE if it's more convenient).
This is pretty much the only acceptable use for a neon screwdriver, proving Live; even then they're not 100% reliable, and are all but superceded by the non-contact type tester for that purpose.
The volt-stick and neon screwdriver should both be regarded with similar levels of suspicion when it comes to proving dead as neither is even close to foolproof.
I don't like to get all holyier than thou over safety on forums like this, so if it's good enough for you, then fair enough...
But what I would say is that whilst there are some scenarios where they're appropriate, I would absolutely kick a Spark or IC Tech off site if it came to my attention they were relying on one as their only or primary means of proving dead.

I shall shut up now, as I'm not a qualified electrician, and I would not want anyone to get hurt as a result of anything I say.
I always have one in my pocket, Some are better than others, but they are never great. I tend to use the test screwdriver for screws which are too large , so gets damaged, then I just get a new one. The last one was just over £1test screwdriver that is actually serviceable as a screwdriver? Every one I've ever owned had been made of Edam.
