I've been using reusable sanpro for many, many years. I started with a Mooncup, but a few tears ago, switched to pads.
I have some by Cheeky Mama. I bought them about three years ago, when they were the only ones I'd heard of, so I didn't really shop around.
They are ok, but I do find they slip round, unless you wear the right pants!
Last year, I bought modibodi period pants and I prefer them tbh. Sometimes, at night time, I wear the CM pads with the modibodi pants and that works well. Annoyingly, modibodi pants have to be washed cold, apparently! I ignore this advice tbh, as I'm not doing a whole wash for just a few pairs of pants. I chuck them in with everything else. They have got a bit worn as a result, which is annoying.
One other thing to consider is that you need to carry the used ones round with you all day. I work from home, so it isn't an issue, but you would need to have a plan if you WOH all week. They do sell wet bags, so you can just put them in there, but a few changes in a day means you would have a few to carry. So you couldn't wear them all day without a handbag or anything. If you're used to disposable pads and tampons, you might be used to popping a spare or two in your pocket and that being that. It isn't a bad thing, just something to consider.
