I use the ezyline - it is just the right size between the 2 poles on the kitchen, so it remains stuck on the whole time we are out.
The benefits for me is no pegs, I can hang each piece of washing per section of line so I can nearly fit a whole load of washing on 1 ezyline, quick retrieval and easy to use one handed.
I also use 3 at home....
