I saw a review of these in the equipment review section. They are very good and robust. One of the reasons Oxfam came up with this idea is that shipping jerry cans into a disaster area means shipping lots of fresh air. These buckets stack for transport and Oxfam can ship many more than jerry cans, They don't tip over like wobbly water carriers and as said, can be rinsed out. Good product - good cause.
I bought one of these after reading http://www.ukcampsite.co.uk/articles/view.asp?id=471. We have found it excellent for camping, easy to fill, use & clean. We store in our washing up bucket. Fantastic product!
I love it! We always fill up a 5l bottle for drinking water, but my daughter can't control the weight to pour, so I always have to stop what I am doing everytime she wants a drink. The tap on this and the fact that it can be kept clean enough for drinking water means problem solved!
