Best hot/cold travel mug I've seen, and I own a Yeti.
This is probably the best stainless insulated travel mug deal out there at the $20 price I bought it for. I have a Yeti 30 oz that I love for taking coffee to work because it holds a lot more than I'll usually drink and keeps it hot as long as I want coffee during the day. I bought this specifically for taking a larger cold drink with some ice to have a cold drink at all times during the day, and it's perfect for that (though I'm certain it's just as good for hot as the Yeti). It comes with a plastic straw, a metal straw with silicone tips for each end (one for comfortable mouth-feel and the other for alleviating noise from the metal on the bottom inside the mug), a straw-cleaning brush and a carrying bag for those accessories. Leak-proof aspects of this item’s lid greatly diminished when using the straw through the lid opening, but knockovers are still MUCH less dramatic than with other types of lids/seals! The most endearing feature of this mug is the fact that its lid SCREWS ON! It has a very nice silicone seal that snugly positions the pour spout/straw hole in whichever position you wish to have it (for left-handed or right-handed use). This is watertight, even turning it over and shaking it... I mean, there's literally no way it will leak accidentally. My Yeti fits deep enough in a side pocket of my backpack for the trip to work that I don't worry about it falling out when the zippers slide a little and even then it has fallen on the ground a couple times; this is too tall to fit in the side pocket and I was worried about laying it sideways in the top compartment of the pack due to possible leakage. NO WORRIES there, it DOESN'T LEAK! A tie for favorite feature of this mug is its ability to hold the contents at a temp cold enough that, with about 1/3 filled with ice and filled to the top with cold tea from the fridge, it still had ice in it ELEVEN hours after filling it. And that was with drinking from it throughout the day, not just filling and sealing it as it seems some do to get their claims of temp retention. My next favorite part of this mug is the capacity; so many claim 30 or 40 oz capacity only for it to actually be less than that, or it's measured at waterline. This mug holds a SOLID 40 ounces with room for the lid to be screwed on. So for coffee, you're getting the full 40 oz. For cold beverages with ice, it depends on the amount of ice used, but it holds temp so well you don't need a lot of ice. The color is cool, the finish seems sturdy enough so far. The silicone seals on both the lid seal and the spout seal are very nice material. The plastic lid and spout slider are nice and solid, and the handle is comfortable and seems well made. I paid almost twice as much for my Yeti and this is BETTER. Better capacity, a handle, screw-on lid that's totally leak-proof. Temp retention is probably the same. Highly recommend this item!

Actually 100% leak proof
I couldn’t be happier with this tumbler. It’s large, great colors to choose from and IS leak proof. I tried to make this cup leak but would not. The only way it leaks is if you utilize the straw. I have bought so many tumblers that made this promise but they would always leak fairly easily, without even trying. Held up great after dishwasher and still doesn’t leak. It’s a little heavy but the large handle makes it comfortable to hold even for men with larger hands. Comes with 2 straw types and a straw scrubber. Fits in car drink holder. Great for hot and cold drinks. I can’t attest to how long it keeps drinks hot or cold bc I drink my coffee fairly fast and drink water and soda at room temperature (sensitive teeth). The price is excellent compared to other tumblers that make the same promises $55+ and up. That’s ridiculous prices IMO. I would recommend this tumbler to any and everyone. May be a little heavy for younger kiddos.

Great Insulation, but can be pretty heavy
We bought the 40z cup in pink and blue for my mom. She’s a driver and her job usually requires her to be on the go all day in vehicles without air conditioning. This cup has worked great so far for her. First of all, she loves the color. We got it in pink, but we made the mistake of dishwashing it, so it’s lost a little bit of it’s color, but still is pretty vibrant, nonetheless. I’d definitely recommend gently hand washing. It’s a perfect size. It fits sung in not only her car cup holder, but in the cupholder on her bus. Best of all, the insulation works great. It keeps her water cold for the entirety of a 6-8 hour work day, even when it’s warm. It hasn’t leaked or spilled so far. She also loves that it comes with a straw, which is perfect for water, and a spout, which is perfect for iced coffee and tea. The only minor downside is the weight of the cup, which is to be expected, given that it’s 40 oz. and made of stainless steal. However, the handle on the side helps a great deal with this problem. The lid can also be pretty difficult to twist off sometimes, if you tighten it too much. We’ve learned how to easily get it to come off though, by running the lid under warm water. Overall, the cup is a great value and is quite effective for its affordable price point.

Good quality
This has been really good. Had for a while now and it all still works, seal is good still nothing had broke yet. Handle is nicely built and the metal straw is nice too. Also came with straw cleaner.

5 stars
This tumbler is so nice and affordable. I got it because I’m prone to getting dehydrated because I just don’t think about drinking water. This has helped and been really nice at keeping my water cool.

Does not keep cold for 35
This cup shows on the website that it keeps things cold for 30 hours. This is not true. You will be lucky to get a 10 hour day. Saying that the cup was only $19.99 so you get what you pay for. If you’re looking for a well insulated cup this is not the one. I do like the way it looks, and it is big at the top. There is no problem putting ice in because you will need to add more. I’m going to keep it because it holds 40oz and it will be great around the house.
