Kids & Toddler Cups with Straw - 4 Pack Spill Proof 8 OZ Glass Mason Jars Smoothie Snack Cup with Sleeve +4 Leak Proof Lid +8 Silicone Straw with Stopper, BPA FREE Baby Christmas Gift Tumbler Drinking

Overall I love these cups. I love that they are glass and silicone only, I love the colors, I love the size, I love the extra straws and cleaning brushes that come with them. With that being said, the lids are a little hard to screw on straight and when tipped sideways liquid will dribble from the gasket on the lid. But are there really any sippy cups that don’t do this?? They are not 100% perfect but I think the pros definitely outweigh the cons.3 month update!To all of those saying it’s impossible to get the silicone sides on and off… peel them off then flip them inside out and roll it back on and it works perfectly. We’re loving these cups. They can take a hit! They’ve been dropped 100 times. I’m still loving how easily everything can be cleaned and there’s no pesky little places for mold to grow!

The lids go on rough. The silicone sleeves don't come off without a serious fight. With other items I have when put into hot water the sleeve becomes more malleable and slides off for complete cleaning... Not these. Finally got one off... can't get it back on There's a big gap between the sleeve around the bottom and the glass. It makes it harder to clean and water gets stuck under there. Also that gap makes the bases unstable and wobbly. We tried for months to make these work. They just aren't good. Way too expensive for the hassle of the poor design. Go with something else

The silicone sleeves are a little hard to get on but I like this my kid's can't take them off. They have been dropped thrown and everything else still in perfect condition aside from a dent in the lid. The seal is slightly hard to get in right but fits perfectly once you figure out how to place it. I do wish they came with extra silicone straw silencers.

I received our order today and was disappointed in the seal for the lid and the amount it leaked from the rim. The seal inside the lid does not properly fit making it very hard to open and close. Due to the seal not being proper, it leaks so much that is causes a big big mess. The cups are very cute and easy to clean, but leak a lot.

Poor quality, lids don't fit well and impossible to sleeve off to clean.

These came yesterday and I was really pleased with them. I got these because I'm trying to stay away from plastic and my 2 year old daughter loves my mason jars I drink out of. They all came in good condition and she loves them. I love that it is just glass and silicon. Not sure if she'll find a way to dump them yet but they are so cute and she really seems to like them.

I do like the idea of this cup and it does work, however the lid to the cups is very hard to screw on and sometimes cross threads. Good product for the price.

These cups are awful. The rubber piece on the lid is too large and the rubber on the outside is too small. They do not go back together easily AT ALL. Don’t fall for the cuteness.
