First there was the idea to buy a 1-fold timer. But I am really happy that I chose for the 2-fold. Easy to use, very good signal (you'll hear 2 rooms further) and a non-issue if the roast in the oven and the potatoes are by 2-fold parallel setting on the stove. We use the alarm clock for setting the washing machine in the basement ... The suspension has also been important for us as we have the old "egg timer" hung on the wall on a nail. Really great - highly recommended!
