40 oz Tumbler with Handle, 2-in-1 Straw and Sip Lid, Leakproof, Dishwasher Safe, Insulated Stainless Steel Travel Coffee Mug, Keeps Cold for 34 Hours, Fits in Car Cup Holder (Midnight)

I tried my mug out this morning to see if it truly would stay hot. I had a major event to set up for and I know it was going to last 3 hours, and I made a hot coffee before I left. I'm truly surprised and shocked to say that when I got done at 11:30, 3 and 1/2 hours later, it was still hot and I mean hot. Not lukewarm, but truly almost as hot as when I left the house. I'm truly amazing impressed and I needed everyone to hear it because I'm the most skeptical person in the world not expecting a quality product. Not only that but it's a big giant mug which I have been searching for for years. I want to drink for several hours and there never seems to be enough. I don't normally like mugs that have the thin bottom because they tend to spill but this one is very sturdy and the best part was that it fit in my cup holder in the car. Job well done guys

This mug is great. 50oz to hold whatever liquid you want. It stays cold all day. I do flavor water everyday and it’s amazing. Ice cold all day. 100% must buy. Also the fact it’s dishwasher safe. I bought the black and green one. I might have buy a couple more. They also fit in the cup holder while you’re driving. My mug tipped over and no dents. The water didn’t spill out either

I take this everywhere. It makes me drink more water. It's easy to clean and fill and has it's large enough so you don't have to refill that often. It fits in the cup holder in my truck. I liked it so much, I bought one for my friend and every member of my family. I got a great deal on these mugs!

Bought a new MX6000 Kubota cab tractor & it has limited space inside but does have a cup holder. Decided to try this 40oz tumbler & it has worked out perfectly. Fits the cup holder snug & does not budge over rough terrain. It’s given me the extra hydration capacity. I fill it with ice, then water, & it still has ice at end of the day. Very pleased.

Great price and design and great fit for 2020 Equinox cup holders. I was unable to accurately determine before buying whether this has any sort of built-in non-slip bottom. It does not, and honestly that is the only thing that is keeping this from being an affordable king. The Amazon AI said that there WAS a non-slip bottom, but I couldn't find any info or review that might have given the AI that conclusion. I bought an add-on anti-slip rubber foot via adhesive, but it reduces the bottle's already-somewhat-precarious stability. Description doesn't specify included straw diameter. It is 0.32" not 0.39" (slightly larger common size). Bought a LUCKINEE tumbler strap to improve travel friendliness.

Great cup. Keeps ice for a long time and I prefer the straw in the middle opposed to the one on the side if the lid. It is east to clean and seems really durable. And the capacity is great.

It's perfect! It keeps my ice water cold for at least 24 hours. The screw-on lid can be placed for either a right or left hand use! (Very thoughtful!) The hole for the straw is in the very center. It truly is dishwasher-safe. (Even says so on the bottom!)If the straw isn't being used, it really is leak-proof. (My dog knocked it off a table onto a tile floor and not one drop leaked.) Fits in my car's cup holder. I love it!

This tumbler is amazing! Why pay 4 times as much for another one that would break, leak, or not keep your drink cold? I even bought the silicone ice cube tray from Powcan. Let me tell you, it truly keeps your ice-cold drink ice-cold for over 30 hours. Amazing product, amazing quality, at an even more amazing price. Totally recommended.
