I purchased three of these bags and am, on the whole, pleased with them. I would not say that they are particularly space saving as they are quite large. However they do away with wobbly stacks of duvets and pillows. As I wanted to lift mine onto the top storage area of my wardrobe it would have been very useful to have had handles on the bags. I was struggling to hold onto a bag and climb a stepladder at the same time. The last bag I attemped to lift, although not full, split all the way down one side when I tried to grab it and lift it up.So, maybe they are not as strong as you think!
