These cups are decent! But in my last 2 packages, literally every other cup is stuck to the cup beneath it pretty firmly, so every 2 cups are stuck together. So they must be separated if you don't want to use them up twice as fast, by prying them apart with 2 hands by the rims, the part where your mouth goes. Hope you washed both hands before you grabbed that cup really quick!This sucks. It feels avoidable, since I've never seen this happen with any other cup/brand I've ever used.

Over half the cups stick to each other... so much so you can't separate them. The red coloring comes off easily and in the cups that aren't stuck together... you find pieces of the red coloring inside the cups These used to be great but they must have changed where or how they're made because the quality has definitely suffered.

I buy these cups every 2 months and never had a problem. But in the last few months, I've been purchasing them and a few cups have had slits in them. So in this pack, I have to look at each cup closely. It's very annoying when you take a cup and put a liquid inside a few minutes later it comes back out. I've never experienced this before. I'm going to continue to shop at Sam's Club I just won't buy those cups any longer.

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.

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

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!

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.
