Avent BPA free 260 bottles - anyone else find they leak?

[SuzysZoo]

Hi - the title says it all really. I love these bottles but they leak from time to time - has anyone else found this. It may be just my user error in which case any tips greatfully received. It seems to be just the new BPA free ones, not the old style.
Thanks
