Turbo timers have their place, in earthmoving equipment they are almost mandatory simply because there is no way an operator (especially if he isn't the owner) is going to spend 2 or 3 minutes of his smoko and lunch break sitting in the cab waiting for the engine to idle down.
On the other hand maybe life is just too short to sit in your Hilux twiddling your thumbs while the engine idles down, I can relate to that.
Bogaard make a very good product, and it's designed, made and serviced in Australia. Has been widely used commercially (earthmoving, trucking etc.) for a long time and has a proven reputation.

I started life with nothing, and I've still got most of it left
