Cons: None yet
The bags are super cool looking. I hang it from a hook as a hamper, fill it, throw it in my car (no more dog hair on my laundry in the backseat) When I pick up my clothes, my drycleaner gives me everything back in my neat green bag. When I get home, no more gnarly plastic and I take the clothes right out and hang them up. It is SO much easier to find stuff in the morning.
The eco-aspect is awesome but I really love how organized my closets are.
