I had the version originally put out by Ken Brooke many years ago and also the "improved" version marketed by Paul Stone. Both of these were breakable and rather fragile, but the trick was worth the necessary care.
The current Tenyo version is, of course, plastic, but it looks much more substantial and is realistic enough to use, I believe. I just keep wondering whether it screams "electronics" to a modern audience. Those that are familiar with the trick realize that it has nothing to do with electronics, but it would be a convenient explanation used to dismiss the trick. I have scrupulously avoided things like magic apps, which have no mystery at all and are only useful as curiosities.
Another concern is whether any trick using an incandescent type of bulb is not dated. I guess the only thing to do is just start working with it and see how a modern audience reacts. I think it’s a cool trick, but that means absolutely nothing to the audience. I’ll report back later.
