I LOVE them! I have a V1 and a couple of V2s, and have my eye on more I would say that for reliability, the minkee outer ones are a bit better, as the cotton outer ones do tend to wick after a while. But they are so pretty they make up for it I just change them a little bit more often.
I have also used the minkee ones at night (using the night insert that they come with) with success!
