I haven't tried this particular type but bought a couple of sets from ebay sellers awhile ago. I found they were okay if you're happy to buy some bamboo or other more absorbant boosters and some well fitting covers. These cheaper nappies often don't have good elastic for containing poo, and only being cotton, don't tend to be as absorbant as other styles. Having said that they are cheap, and might be worth a try.
One set I bought that didn't work very well my nephew now uses for his teddies
so not a total loss.
