The hemp inserts are great. My baby can pee through a microfibre insert in 45 minutes to an hour. The hemp inserts reliably last 2 hours and sometimes as much as 3.
Buttons inserts not only fit in my Buttons diaper covers they also fit my Best Bottom covers! Love them all. They are nice and soft as well as absorbent. I love the snaps on the inserts, it makes the process of changing a diaper so much easier.
The Buttons cover with a tri-fold plus the daytime insert is our standard nighttime diaper. Not a leak yet.
I've only taken these inserts out on one spin, but so far they seem very absorbent. The only issue I see is that the blue edging thread on one of the inserts is starting to come out. I noticed this after I finished prepping the inserts, which surprised me (so soon?).
I purchased the Hemp/Cotton Daytime Inserts and I love them! I tried Best Bottom's inserts because I heard how trim they were. These inserts remind me a lot of those, they are trim but what I love about these is that they are much softer and wick moisture away from baby's skin. So I love that I don't have to add a fleece insert on top to do that. I also got the microfiber nighttime insert. This is so easy. The one thing I have disliked about cloth diapers is the nighttime diapers. I usually have to add 2 extra inserts to a fitted or prefold diaper and they are so bulky. This is much trimmer and simpler for me. Love this system!
