🌈 Optimized Color-Changing Cold Drink Cups Review

The cups are very cute and I was very happy with them, but I didn't get all 5 cups. Straws and lids came with 5 but only 4 cups. Edit: A few days after I posted this review, I received another package at my door, it was another set of mugs! I didn't ask for a refund or replacement, they just sent it! Increase the stars to 5 based on customer service!

Media could not be loaded. I'm really impressed with these mugs, at first I was really scared to buy them based on some of the reviews. Some reviews said the mugs didn't change color, but I found all mine changed color. Before using the cup, I pour warm water into it and rinse it, then add ice water into the cup and it changes very quickly. I liked that I can customize them and they do what they say. I definitely recommend it and I will buy more

Much better when I bought these than a Starbucks mug which has sold out everywhere and is now for sale on eBay for over $100. My daughter (14) loved the interchangeable cups so I bought her this set. She was pleased with the color change and the fact that she had five instead of one. Great gift for teenage/teen kids, especially kids who have everything and you have no idea what to get them and maybe, like me, don't want to spend a fortune dreading the cost of college.
