[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 love these tumblers! Even better than the big brand because of the handy pop out carry handle on the lid and the option to lock the spout and throw in your bag without any worry of spills! Took this for a full shift at work and it stayed cold all day long! I am going to recommend this brand to my friends because it is better than any comparable item on the market.

[This review was collected as part of a promotion.] These cups are of good quality, compatible to carry in your car's cup holder, long-lasting for cold drinks, spill-proof, stainless steel so easy to clean, nice colors and large capacity, the only complaint is that the duration for hot drinks is short, otherwise I highly recommend it.

[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!

[This review was collected as part of a promotion.] I used this tumbler on my way to moms for the holidays and I put my hot cocoa in here it kept it hot for four hours and it tasted like I still made it too.I also used one to sip my vegetarian broth out of for lunchtime ,these are so useful and so easy to clean just toss in the dishwasher and you are good.

[This review was collected as part of a promotion.] These cups have been the best! They keep ice for well over two days! The capacity is 40oz and I love it as water drinker. Cleaning is fairly easy and the design is cute and modern. I would buy these for the whole family.

I have purchased the viral Stanley quencher, and this dupe is better + so much cheaper! As a walker, I always want to carry my water bottle with me, + I love that I can fully close this tumbler while I walk so I don't spill all over myself! If you are looking for a staple water bottle that does it all, I highly recommend!

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.
