Review: Save room in your kitchen with this one - The one that never drips. After experimenting with numerous tumblers and facing constant disappointment, I have finally found the perfect one that checks every box. What sets this tumbler apart is its intentional, minimalist design. Unlike my bulky 40oz Stanley, which frustratingly refuses to fit in my car’s cup holder, this sleek model slides in effortlessly. The engineering is also superior; the weight distribution remains balanced even when full. It avoids the top-heavy, cumbersome feel of other brands that are either too wide at the brim or excessively tall, making it a breeze to carry throughout the day. The aesthetic is equally impressive, featuring a sophisticated, dark matte purple finish. Its thermal performance, however, is the real standout. During my most recent test, I poured in two refrigerated water bottles with no ice; the water remained crisp and cold for a full 48 hours, only beginning to lose its chill on the third day. I have no doubt that adding ice would extend its temperature retention even further. This is an easy 10/10 recommendation.
Review: Better water bottle than anyone else - Will definitely buy again! This is my second Simply Modern cup and will continue buying the brand. Bought many months ago and still holding strong. Clean look, fits in regular cup holders, useful handle, straw hole is leakproof (besides straw itself). Straw is bendy and durable. Lid is leakproof and tight seal. A cheaper (better) cup than the other big brand. (You know the one)

### ⭐⭐⭐⭐⭐ Great quality!
*by P***E on November 24, 2025*

Simple cup has quickly become one of my favorite drinkware brands. The quality is impressive—lightweight but sturdy, with a sleek design that’s easy to hold and fits perfectly in cup holders. One of the standout features is the insulation. My drinks stay cold for hours, even in the heat, and hot beverages stay warm without the cup getting too hot to touch. The lids seal tightly and don’t leak, which is a huge plus for anyone on the go. I also appreciate the variety of colors and finishes; everything feels modern and thoughtfully designed. Overall, Simple cup delivers on both style and performance. It’s a reliable everyday cup that feels premium without the premium price tag. Highly recommend!
