The Safe Starter 2 Pack Nipple Replacement Pack, Flow 1, White

I ordered the safe starter 9 oz bottle and 2 slow flow (stage one) replacement nipples because my baby is breastfed. Sadly, I received 1 medium flow and 1 slow flow nipple in the box! Good thing I checked as we are already battling with nipple confusion and a medium flow would have been a disaster.The bottle itself doesn't have any markings in the inside so you can't easily know how much liqiud is in inside! The markings are only on the silicone sleeve (which is a pain to get on by the way). This is a major design flaw compared to other stainless steel bottles like Pura and Kleen Kanteen that have the ounces etched into both the outside and inside of the bottle itself.I wanted to like this bottle but I think I'll be sticking to Kleen Kanteen and Pura.

These nipples were horrible. I ordered 2 boxes and I've already discarded 2 nipples. the rubber part around the rim started to peel and milk leaked everywhere. Very poor quality. I would like my money back but discarded the boxes, not thinking they were this poor in quality. When we first purchased these bottles, the nipples that came with them never gave us any issues like this. Don't feel amazon should be selling defective products. Very upset with this purchase

These are supposed to be slow nipples, but when baby tried to drink with them, he kept coming because the nipple was too fast for him

Worked like a charm. No leakage problem like a reviewer had stated. Glad I ignored her complaint, totally unwarranted, posssibly they had not seated item properly.
