I'd have to second the Honeychild's
We do a 30 day money back guarentee on all of our nappies as well as the 1 year warranty. So you can use it as much as you want and if you're not happy with it in those 30 days send it back for a refund
If you were going to get a trial nappy, I would advise to get the night time trial as that comes with 2 inserts and a free booster for $42.
Let me know if you have any questions, always happy to help
