Bests & Worsts Reviews from Amazon

These cups are great, but the nipples don't last very long with active toddlers. They bite them and play with them, sometimes jamming their fingers into the slit. I'd guess a nipple lasts a month of regular use. THERE IS NO WAY TO GET REPLACEMENT NIPPLES. I have bought at least 6 sets of the grippy spout and the matching sippy cups just to get replacement nipples since my kids like them. It's more expensive, yes, but I also am just throwing these cups away because they are completely useless without the matching nipple. Do yourself, and the environment, a favor and don't get invested with this brand. It's unconscionable they don't sell the replacements here or on the Philips parts website (which has replacements for other cups).
