I really wanted to use them with my first baby, in fact I went and bought a load (I think I have about 12/13 of them, all different styles). No matter which one I used, they always seemed to leak out of the back, sides, every part where they could leak they leaked, and I found it too much trouble in the end. I tried them again (after about a year's break) and this time I found they weren't leaking so much but they were only lasting about 2 hours so I had to be on top of the ball otherwise I would have a really wet baby. My baby never has nappy rash (he's had it a total of about 8 occasions (days or part days) due to teething only) so I'm not too concerned about disposable nappies on his skin. It's a shame though, I really did want to use the reusable ones and I have some really cute ones.
