washable nappies

Tricia
Has anyone had any experience with washable nappies?? 
I really want to give them a go. I was looking at the little lambs nappy + wrap combination 
I know they also do the pocket nappy which is more of an all in one type- but I have read reviews that these are difficult to get a good fit with the poppers and often leak. 
Any advice or other ladies thinking to use these let me know!!! :) 
Thanks Trish x
