I have a minilala - and I haven't had any probs with it yet - although I haven't had it very long (couple of months?)
I just wouldn't leave it on for more than 2 hrs
Oh, and I didn't get mine from minilala direct - so can't really help with customer service.

As for CT - when I first went cloth (when DD was 8mths old) they were the only nappies that worked really well for us - but as she has gotten bigger they aren't really working well anymore.

Pop-ins are my fail-safe nappy!
