Bought these as an add-on item with a Prime trial, as we were getting very low on our liners supply and needed something to tide us over for a couple of days. We usually use a different product by a lower profile brand that goes with their own nappies, and is similarly priced to the add-on cost for the Tots Bots liners.
I was very disappointed when the Tots Bots liners arrived, and very relieved when my usual product - ordered the same day - arrived a day later.
The Tots Bots liners are very thin both in terms of area and thickness - they are too short and narrow to provide decent coverage in a nappy and we had to use two to adequately provide for wet and soiling incidents.
After a day of using them, we were pleased to give up on them - there was no one-way moisture feature so that when wet the liners semi-disintegrated and were sodden - even light wetting rendered them like soggy tissues. It meant each time my child wet the liners at all, he pulled his nappy off because of the damp discomfort - which resulted in a few puddles on the floor as he didn't always finish before removing the nappy. The failure of the liners to keep damp away from the skin also meant that my son had some nappy rash by the end of the day.
Luckily we only bought the liners as an add-on item as they are definitely not worth the full price, and we have had to stick most of the roll into the recycling bin. Perhaps they only work efficiently with same brand nappies, but we certainly won't be buying them again, because of the poor performance.
