Very good, but watch the air entry valve, 26 July 2010

Very good, the only snag is with the relief valve. I've found on several teats that the valve is still closed (ie. stuck together when manufactured). This is evident when the teat sucks itself into the bottle as the baby creates a vacuum (air isn't allowed into the bottle to equalise the pressure. It's a very easy fix and I would recommend everyone to check before first use. Just look at the small valve and squeeze the two outside edges together. The two 'lips' should open as if they were saying "ooh" and then close again when pressure released. This proves air can pass from outside in, but milk can't escape outwards.Other than that, no leaks and would buy again. Recommended.

Fast flow teats., 24 Feb. 2013

Brilliant product, and brilliant price! Would deffo recommend to everyone, my little girl uses comfort milk which is a little bit thicker so these teats help!

Good teats for hungry babies, 1 April 2013

Wish we had changed to these fast flow teats earlier! Our son was getting bored after feeding for more than 5-10min on the bottle, he ate much more with these new teats as faster flow and he then started to sleep at nights!Started using them as he was 5months old.
