I absolutely love tykables products. The sample Little Builders I bought was highly absorbant, thick, durable (for the most part), and super cute! The only issue I had was that somehow the inside of the diaper had ripped open in the area of the seat. When I went to change into the objectively inferior M4s I had, the stuffing fell straight out.
Aside from that one issue - pretty sure I just got a defective one or something silly - I loved this product and would absolutely buy it again.
