I had/have heavy duty plastic garbage and recycling containers in the kitchen. The one for recycling had begun breaking off in the months, and a change was needed. And this product turned out to be better than I anticipated.  It takes up the same amount of space as the old one, but holds approx. twice the amount!  Yes, you can use it with or without lines.  It comes with 4, and regular kitchen garbage bags work.  And it doesn't smell and absorb odors like plastic.  Easy to clean, and you can use it with or without kitchen bags.
Very pleased, highly recommend.
