I have not tried this product yet but based on multiple reviews these are great bottles so we will see. I don't think all baby bottles are well priced on this website as they are much lower on other places the reason I purchased from here because I had a coupon which end up to be the same price as elsewhere. One thing I did not like is the packaging it shipped in, it came third party not directly from Great Offer Stock and shipped in the yellow envelope but that envelop was pretty bead up and initial package was pretty bent. So would recommend to package this product differently. Most of the avent bottles I bought are glass the reson I got 2 plastic bottles are for my diaper bag so they are not as heavy to carry around.
