I think they are new and beautiful products that you should try and use especially if they are offered for free.

Used these bottles with my first son and it was the only ones he would accept. Bought this set when I found out I was having twins, unfortunately they don't like them due to being in nicu and the nicu used different bottles.

These were so good. I breastfeed for a few months and these were godsent. They were kind of pricey but thankfully I received it as a gift. They worked amazing when transitioning from breast to bottle. My daughter loved it and so did I. I would recommend this bottle every time.
