Good, just not what I needed.
Good product, shipped fast. Cute color and great idea. Only problem is I accidentally left it in my shopping cart and checked out without paying attention. I was doing a little research to find out if it is compatible with my Medela bottles (which it is not). I was distracted by it, and checked out before realizing I left it in the cart.

Love, love love!
This sippy nipple is the only one my daughter will use. She is very particular about both her bottle and nipples. We have tried every sippy cup: Nuby, Munchkin, OXO, Nuk, etc. She even hates the MAM sippy cup rectangle nipples. Literally spent over $100 trying to find ONE cup she likes. I ordered a Thinkbaby sippy bottle and she hated it. On a whim, and desperate, I decided to try the nipple in her MAM bottle and it fit perfectly! She is doing so much better with her milk now! If you have a particular baby like mine, try these nipples on your other bottles, it might just work!

The handles rotate freely, sippies vacuum up
The handles are helpful, but do not screw on, they sit on the bittle under the cap like a washer, and can spin.The sippy attachments are not good. My baby can hardly suck liquid iut of them before the pressure implides them, and she has to take it out of her kouth to let air suck in through the hole… ish. I use Lansinoh fast flow nipples. They fit the lid perfectly, and the air vent works much better. Are also silicone.Imo, the handle is hardly worth it, this is over priced. Would not buy again.

Ease of product is great! My son transitioned from his dr browns wide neck bottles in only a day! Great products! We used with our first son too and he still loves his straw bottle!
