The only slight drawback is the smell - the laundry has when wet a relatively strong smell (it will probably be citrus, I can not assign). I find this smell as pretty uncomfortable, but I am very sensitive in this area and it does not like it when my laundry smells of any detergent.
To my delight I have but found quickly that the smell completely vanishes when the laundry is dried in the air (in the house). Dries the laundry in the dryer to stay, there are often a slight smell, but it really is very weak, so it is not very bother me.
For me this is not a reason not to buy.
