Washing with the ecoegg is really convenient (no spilling of powder or liquid detergent), fast (fixed placed in the machine - dosing omitted), pleasant for people with allergies, European product (livelihood in other countries is maintained) and the environment would be double - no water pollution / transport costs account for and properly clean it is ... only if there are really 3.5 ct per wash load, I do not quite. Just I'll know it when my next refill. Too bad, because the egg does not have to hide behind as an advertising promises!
