My life has ben saved by this.
You can't poo on* it until you've tried it.
*"Poo on", here, meaning make fun of it, say you'll never use it, etc. Not a 'poo' reference, in the classic form of the word. It's like when Madeline's teacher says "Poo, poo" to the little girls when they're not doing what they're supposed to.
