I have purchase these several times and usually they are ok but the last package I have had several of them that are stuck to other cups. Cannot separate them. It's like every 3-4 cups then you come across two that just will not come apart.

After you start drinking out of this cup, the red plastic covering starts to peel the way where your lips go on the cup. I stopped purchasing these right away. I have no idea how much I have ingested of that red peeling stuff.

Love these cups. They’re such an awesome price for the amount of cups and they always work well. No issues. I buy them time and time again!

The cups were covered in plastic dust and were never cleaned from the factory. I need new ones shipped out

I received the red cups and they were unusable. Most of them were stuck to the next cup and most had red ring on the inside of the cups in the bottom. It was as if they had been messed up in manufacturing.

Like a great value water bottle to a Dasani water bottle

We can't use these cups, plastic comes off in drinks.
