CopcoSierra Single Wall Tritan Cold Tumbler with Straw and Spill Resistant Lid, 24 Ounce, Set of 2, Royal Blue

I like the product and use them every day. The only downside is that sometimes the rubber seal that is on the lid can dislodge and it is hard to put back in. It would be great if they sold the lids as a separate replacement part so that you don't have to order the entire cup.

Love that the top screws on

These hold up nicely in the dishwasher, including the waterproof gasket on the lid. They last about a year through heavy use.

Ever since I bought my first one in 2006 and it was mistaken for just an ordinary coffee cup it was thrown away after my shift on transit bus when I forgot it behind my seat. I immediately went to buy another one shortly after purchasing #2 maybe a year it was dropped full on asphalt on the side of the lid and it cracked but not so badly that I was not able to use it until recently when it has started to leak I'm still using it but it could snap the piece off anytime so bought one as gift and another for myself

Owned many different iterations over the years, don’t trust it to be dishwasher safe, it will warp very easily.

Nothing

Nothing to dislike here. They work great.

This is my 2nd set. I hand wash because first set got cloudy over time being run thru dishwasher. Be careful screwing on lid even or you will be wearing your drink. I do enjoy the convenience of these glasses with straw. I drink my pitcher of water every day. Helps me keep track of what I drink.
