Great Everyday Cup

I've been using this daily and it's honestly been really good for the price. It keeps my drinks cold for hours, and I love that it doesn't sweat on the outside. The purple color is super pretty, and the straw lid makes it easy to carry around with me. It feels sturdy and fits nicely in my cup holder too.

great buy!

the cup is great keeps hot and cold. kept ice for over 12 hrs. pretty good for a 10.00 cup. The one thing I don't care for is the suction power you need with the straw. it's truly leak proof so I get why you need to use a little more strength. aside from that the cup is awesome!

while I absolutely love these, there should be a note somewhere about how to take the lid apart to clean because like the little air intake gauge mold can grow there and there needs to be like a pack of replacements for the lid made. other than that it keeps my drinks cold for a really long time
