I am pleasantly surprised with the Ecoegg laundry egg, it produces clean fresh smelling washing and no more dried up powder mess in the washer dispenser drawer, which is a bonus. I would recommend it. However I would not recommend the dryer eggs, unless you like your dryer to sound as though it is being smashed to pieces whilst it is being used, which means you can't have a conversation or listen to to TV (unless your dryer is outside in the garage I guess)
