Works as expected ....except I didn't expect her to be fascinated with open and closing it. Oh well. Lol

I like the simple design of the cups. It has the features I am looking for in a toddler's cup: insulated so it's good for cold milk and juice; fewer parts to assemble, easy to clean - especially the straw, it is bigger and easy to clean with a straw brush. The straw has a design to prevent leaks. I'd say most of the time it doesn't leak, but when my toddler hold the cup upside down it does leak a few drops. Overall these are good quality cups at an affordable price. The best part is they sell replacement straws for a very reasonable price! I've repurchased a total of 4 cups and 6 straws, just in case they get discontinued in the future.

My toddler loves the straws and the cute colors.

Straw controls liquid coming through, so no big gulps or choking. Easy to clean and put back together.

My girls love this cup! They always fight over it, so luckily we have two now. The straw pieces are really easy to clean and I like that it's not a ton of parts.

One of the two cups leaks from the base of the top, the other one works great. Not insulated enough to keep drinks cold in a Georgia summer but better than nothing. Good size and easy to wash.

I like the silicone straw cups a lot. It's easier on my toddlers teeth. Straw cups were also recommended over traditional sippy cups to help with speech by my kids' pediatrician. The only downside is these cups leak much easier than traditional sippy cups. You'll need to watch carefully to make sure no one is making a mess.

Love that they fit in the cup holder. With the straw was easier to re-thread during reassembly. And there is no air intake valve, so my LO has to pause and wait for the air pressure to balance. Not all bad,just inconvenient when needing water fast. Also love that it comes completely apart for washing.

I love these bottles. Some other brand bottles has a pointy plastic sticking out near LO's nose when the straw is open. On many occasions it makes me nervous when little runs and falls with that bottle. Thankfully this bottle is smooth and dome shape which put me more at ease! The pressure on these are better too. However one bottle has a valve that leaked everywhere on several occasions. It ruin several books so we are extra careful with that bottle. still our favorite bottles for LO compared to others

Leaks from everywhere; around the lid threads, out the straw, and when the straw is initially opened it flings water everywhere. Leaking is worst if there's any temperature change. If the liquid is cold or the outside temperature is hot. I want to like them but they've soaked out the diaper bag, carpet, car, etc. more times than I can count.
