I used to use them all the time. OF course, I just made flannel liners for them instead of the flushable ones. I love the design of them and they have great customer service.
I actually have a couple of the covers up for sale if you're interested (red and orange mediums I believe). I don't use them anymore cause I switched to my own pocket design.
