The slinki minki super soakers are quite bluky. I only use ours at night.
I got rid of all my MF inserts and got petit desous bamboo inserts. I use them with easy peasy hemp boosters we get about 4 hours out of that sometimes longer
I know they are around £5 each but they are so worth it.I just got a few at a time, I think i have 8 now.
