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

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.

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.

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.

It was a gift for my husband and he loves it! The straw makes drinking so convenient and easy so he ends up drinking more water which is beneficial! Water remains cold for a LONG time! Good buy! Good quality!

I LOVED THIS CUP! I went and bought two more! It is durable, beautiful design, keep your drinks ICE COLD, the ice lasted over 24 hours in my cup. Fits great into my car cup holder not issues at all. Fits the cup bag holders. Spill proof does work when the straw in not in the cup! Great gift idea.

Me encanta tiene una gran capacidad para llevar dos botellas y media de agua, y mantiene fría con hielo muchas horas es una maravilla
