I have been using these for several weeks, mostly at night when I tend to leak quite a bit.
Sometimes I leak through on particular heavy nights but most nights the level of absorbency is sufficient and now that my breasts aren't leaking so much they are perfect.
I like the way that I can reuse these and there is little outlay compared to the ongoing costs of disposable pads.
I also like the environmental factor, some disposable pads are individual wrapped and therefore have a lot of waste.
