COKTIK40 oz Tumbler With Handle and Straw Lid, Vacuum Insulated Travel Coffee Mug Stainless Steel Insulated Cup for Beverages, Leak-proof, Cupholder Friendly (Lavender)

Fantastic mug. Easy to clean, keeps drinks the right temp for longer than I need it to. Cute.

Very sturdy love the price keeps my drink cold it does fit in my cup holder

I am absolutely amazed at how nice this is, especially for the price. The lid fits tightly, it came with a sturdy straw and a straw-cleaning brush, a big foam brush for cleaning the cup, and a silicone bumper ring to put on the bottom of the cup so it doesn't go "clunk" every time you put it down on a hard surface. What a great find for $9.99!

Yesterday morning I filled this cup about 2/3 full of ice, and this morning there was still enough for today’s drink. Now, about 40 hours later, there’s still a bit left. In short, it keeps the cold very well.The tumbler and I got off to a very rocky start, however. Like most of these designed to fit in a car cupholder, it’s fairly tall and a bit top-heavy. No leakproof lid will keep the contents from spilling if it isn’t on the cup. While I was filling it, I clumsily tipped it over. That didn’t make me love it. Then, in my Toyota Rav 4, it didn’t fit the cupholder well. The silicone boot stuck in the holder and detached from the cup. Taking that off only let the cupholder scratch against the metal. That was it for me. I began the process of a return to Amazon. But in using the tumbler, noticing how well it kept the cold, admiring the color (shale), and comparing its sturdy build to others, I decided to give it another chance. I replaced the silicone boot with a more substantial one. Now the cup slides into and out of the cupholder without issues. I decided to keep it, and glad I did. Return cancelled. In fact, I’m so impressed I ordered another one of a different color.I’ve not tested it for hot drinks, but it is more than satisfactory with cold. The build is solid. The handle is metal; how it is fixed to the cup is unclear, but it is firmly attached. Two rivets, visible on the outside of the handle, hold a plastic insert firmly in place for comfort of grip. The lid and straw seem well made. With a little practice one can learn where to start screwing on the lid so the sip hole will end up in the desired position. I haven’t tested it for leaks—that’s not an issue for me—but don’t think it could leak much if at all. The only issue I had with the lid is that if it’s screwed on too tight, it’s hard to loosen.All in all, a great 40-ounce tumbler. Time will tell how it holds up, but now I’m very satisfied with this purchase. I unqualifiedly recommend.

Love the size and the capacity, the handle is beefy. Overall construction is superior. It's ability to keep cold is about three days. Excellent!!!!

I'm very happy that the rubber on the top of the lid is not that complicated and it's in the small size because I don't want to have a difficult to clean it since mold mostly stuck in the rubber lid. This is perfect for me clean and to see what's in it. The color is so pretty too.Water is very sealed there's no leaking when it's closed I'm glad I didn't buy the one that is very popular in the market right now because I hear the water leaked, I'm glad this one didn't and price is very affordable too. It's so generous for the seller to include cleaning stuff for that price I have no complain. Worth the price. It just too heavy when you fill it up with water.I wish they have more sizes like 30 or 35 oz

I LOVE this cup. It’s sturdy and keeps my drink cold. It came with brushes to clean both the cup and the straw and makes it super easy. I love the color, too. I am very pleased with my purchase.

I use this to primary hold cold drinks. It does a very job of keeping cold dri KS nearly as cold as they were coming out of the refrigerator for at least half a day. I drink a lot of fluids. Hence, extra large mug. What I like about the straw feature is the it is wider than most, and it fits snuggly in the hole. There is a rubber piece in the hole that seals it reasonably safe. The rubber part in the straw hole is where the attached rubber plug seals the hole when you are not using the straw. Mine fits easily in my car's cup holder.What I don't like about it is my common complaint with many brands of travel mugs. If you don't want the use the strsw and sip from the side, you may find this cumbersome and messy. There is a lip on the top that's about 3/8 inches high. So when you turn up the mug to start to sip from it, you have to be extra careful. If not you may receive a rush of fluid you can not sip fast enough. This will result in the fluid overflowing the 3/8 inch lip. In other words, this 3/8 inch lip makes it nearly impossible to seal your lips against the sipping hole. This is especially problematic with such a large mug. If it is half full, it takes at lot of effort to tip the mug just correctly so that you don't have 20 oz. of fluid rushing toward the sipping hole. Imagine you have 180 degree coffee in this huge mug, and you have 20 oz. of it coming at your mouth and not knowing where it is in in this very tall bottle. You could get scolded, as well have coffee overflow into your lap and on your clothes. Personally, I would not use it for hot fluids. I bought mine for cold fluids. I don't need such a huge mug for coffee. I have others that are sipper-friendly. Having said that, if you plan on drinking more than a quart of nice cold ice tea over the course of day, you will really appreciate and enjoy this travel mug.
