[This review was collected as part of a promotion.] 5/5 because product works as advertised. The listed functionality is accurate in terms of insulation & build quality. The marketing also seems accurate since the shape of the cup (tapered at bottom) allows it to fit better into car cup holders. Other insulated bottles I’ve used usually don’t fit into cup holders since they don’t have the taper at the bottom. Also, I like that the cup can be opened & securely closed using the sliding piece on top of the lid. In terms of improvements, maybe the bottom and the handle material could be made more “grippy?” The bottom is just metal so I could see it sliding/getting knocked over, and when the cup is full the handle is a bit slippery.

[This review was collected as part of a promotion.] I am loving the Ello Port 40-oz. Stainless Steel Tumblers! These tumblers are incredibly durable, stylish, and practical. The stainless steel keeps my drinks cold for hours—even in the hottest weather, my iced coffee stays perfectly chilled. I also love the generous 40-ounce size, which is perfect for staying hydrated throughout the day without constantly refilling. The handle is a fantastic feature, making it easy to carry around, especially on busy days when I’m juggling multiple things. Plus, the lid fits securely, preventing any spills, and it’s super easy to clean. I really appreciate that these tumblers are dishwasher-safe too; it makes life so much easier. Overall, the Ello Port tumblers offer great value for the price, and I would recommend them to anyone looking for a high-quality, stylish, and functional tumbler. Whether you’re taking it to the gym, the office, or on a road trip, these tumblers have you covered!

False advertising

The iced water doesn't stay cold all day. I have to add more ice after each water refill.

I was really excited an out purchasing this item, But truly disappointed. Ice melts fast and won’t keep your drink cold. Don’t waste your money.

Love these tumblers. Very durable, easy/comfortable to carry and fit perfectly in my car cup holder.

I love this tumbler! It fits perfectly in a cup holder and the sliding lid makes it so easy to travel with so water doesn’t spill out. The carry loop on the lid is also an added bonus.
