I wanted to buy a ready filled bean bag and not have the hassle of trying to get one filled with beans or rice abroad. This double one is ideal as it is very lightweight but performs beautifully. I use it on the ground for macro photography or to rest my Canon 1D and Canon 100-400 lens plus converter on it. There is no problem with the heavier items. Recently I used it whilst in the car with the window down and balanced the bean bag and camera on the window sill. It has a small strap, a few centimetres long, which means it can be clipped on to a belt or a rucksac. It has received 4 stars rather than 5 because it rustles slighty, but this is not a problem when the bag is in situ. I am delighted with my purchase.
