I use them!
Normally I use a Diva Cup (best thing in the world) but I’ll use a reusable pad (I have Glad Rags) now and then around the house on light days. I like to use them overnight near the end of my period, where I may or may not spot and don’t really want to bother with the cup. I also keep one of the small liners in my purse for any emergencies. Usually I don’t go out and about with them- it’s more of something I use at home when I’m just not feeling the cup for whatever reason.
I don’t find them gross at all- washing them is like washing a pair of stained panties. Mine are burgundy, and so you don’t even really see the blood.
Anyway, I don’t use them often, but now and then I do and they are a nice thing to have around. I haven’t purchased or throw away a single menstrual product in four years!
