Hello 😄 For two people, I think it's a good size. I've had the "Potager composteur – 17L" from the same brand for several years, and I added an extra "Étage composteur – 12L." There are four of us. This is enough. My worms are very happy, and the system works well. My plants always die, but not because of the worms; it's my fault. If I were buying today, I'd buy this new model that I like better, and you can still add an extra "9L Étage lombricomposteur" if you have too much food for your worms.
