My favorite tumbler!
This is my daily use tumbler that I have had for about a year. I recently knocked it over and broke my clear plastic lid. The original lid was leak proof where it screwed on, but the space for the straw on top leaked if it got tipped at a slight angle. I ordered a pack of two Stanley blue color tumbler replacement lids from Amazon that matched my tumbler and I couldn’t be happier! The new look with the matching Stanley tumbler lid is perfect! I ordered two more of these blue flowered tumblers and actually prefer the Stanley replacement lids, because now it really is spill proof if I tip it at an angle or upside down with the straw closed. I also like the fact that the straw can be pushed down to close the straw when not in use. My ice water keeps cold all day long. I get many compliments on my beautiful blue flowered tumbler. I highly recommend this tumbler.

Nicely sturdy and attractive
Got this hot/cold biggie mug for a cruise. Loved it! I used it a few times for hot coffee and it worked great keeping the heat for a long period, but my personal intent was using this for COLD - A biggie iced coffee in the morning and iced water for the afternoon. For the Cold use, this mug is Fantastic. Iced water made for the afternoon in hot sunshine kept cold *still having ice in it even when evening time came and I clean the mug out for the next day! Perfect performance. And it never leaked once.

Love it !
I don't have a stanley to compare it to but I love how it fits in a cup holder, it holds lots of water to help me stay hydrated in my pregnancy, and that it's just lovely to look at ! I am not a paid reviewer but it seems well made, came in a pretty matching box with two lids and straws. I'm in Texas and it's hot most of the year, and I'd rather put my drinking water in stainless or glass rather than plastic but that's just me. I have littles though so glass isn't to good for me. I read a lot of reviews that said this kind of tumbler leaks though with kids so I purchased a few goodies for mine and I haven't had any issues with it leaking when tipped. #1 I ordered silicone "Purifyou" 4pk wide straws they had good reviews but the main reason for ordering silicone was because it doesn't make a clinking noise everytime I drink. It's silent so I can take a drink in the middle of the night and not wake my husband or in the day and not alert my kids so they want a sip ! It's great ! Plus I read one reviewer said their child fell with the plastic or metal straw in their mouth while drinking and it was a big medical bill.... I don't need that ! #2 "Owala" silicone boot or bottom protector their 24oz. fits the cup flawlessly and still fits in my cup holders !!!! Reason to get this was so it saved my pretty cup, was silent when I set it down and it looks sharp ! I tried one that looked like a ice cream cone while it was pretty it didn't fit very well in my cup holders. #3 was some silicone pieces to seal up inside around the straw and middle part and it came with a straw topper too. It came in a pack of two and with my wide silicone straw plus this it doesn't leak !!! Super happy customer !!!

Stylish and functional.
Fabulous! The cup holds plenty of fluid and ice for my morning iced coffees with protein shake added. The ice doesn’t melt for HOURS. Very well insulated. Super cute and sturdy. I love leopard print so this is the added bonus. Easy to clean. Very satisfied with this cup.

Beautiful
This tumbler is beautiful. The plastic straws that come with it are flimsy and bend easily. Doesn't keep ice as long as I expected, but still worth it.

Large cup
I like design of cup. It is a little heavy when it is full of ice and water. Was to be expected.

Beautiful!
This is the prettiest cup! I have a Stanley and this cup is just as good. The straw is probably the only difference. The straw with this product might be a little less sturdy and slightly bigger in diameter. However, I’ve had the cup for almost 3 months with no problems. No chipping of the paint, the lid fits securely, straw is great. Best part is the lid screws on and doesn’t just snap in place. If my ice water is left in it over night, it still has ice the next morning.

Beautiful and Mom-Approved!
I got this floral tumbler for my mom for Mother’s Day, and she absolutely loves it! The design is even prettier in person—bright, cheerful, and perfect for spring. She uses it daily for her coffee and says it keeps her drink hot for hours. The quality feels great, and the lid fits securely with no leaks. It was such a simple gift, but it made her feel special, and that’s what matters most. Highly recommend if you’re looking for a pretty and practical gift!

The design on the cup was double printed and made it blurry and "off" it blended the colors horribly. Then in some places it looked stretched so the black had white streaks. Can't speak to the cups usage as I won't use it because it looks awful.
