COKTIK50 oz Tumbler With Handle and Straw Lid, Vacuum Insulated Travel Coffee Mug Stainless Steel Insulated Cup for Beverages, Leak-proof, Cupholder Friendly(Shale)

This is such a great cup! It easily fits into cup holders, has not leaked on me and even comes with a cleaning squeegee for the straw. It keeps my water cold throughout the day and costs a fraction of the other cups like it! I plan on getting another cup to have backup.

Cup was cute and light to carry. Keeps water cold and ice in it for long. Doesn’t spill without straw in it.

My fiance loves this cup! It keeps drinks cold and it so easy to wash! It is also durable and is a great Stanley dupe!

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.

This is one of my favorites due to the size and being able to fill with ice and then still have plenty of drink to take along. The color is beautiful too!My only complaint is that it didn’t fit in my car cup holder with the rubber bottom on it, but eventually the rubber piece fell off and I didn’t know it, so it’s lost.

Okay…first, I’ve never owned a Stanley tumbler or any other name brand for that matter. I can’t imagine what would make one worth so much. I researched a lot of them, and settled on this one for right at $20. It was well worth it. It does have to be washed by hand, which is no big deal to me. It came with a straw cleaner and a sponge cleaner for the tumbler itself. Those were nice extras. The lid turns easily and settles perfectly to drink from the spout. It has a great spout lid that snaps in place well, and when opened, lays all the way back out of the way. The straw hole is centered in the middle and has a rubber closure. It fits perfectly, and is good quality. The cup part also feels quality and has a normal taste. It came with a rubber attachment that fits onto the bottoms to make it more stable sitting on slippery counter tops. I love the handle. It’s smooth and easy to hold. I tested it with ice at starting yesterday morning, and it still has some ice left in it all the way to the next evening. That’s about 36 hours. After 24 hours, most of the ice was still there, and I even poured luke warm coke on top of it. Still didn’t completely melt at the end of the second day. It came in a very nice box, is a beautiful color, and had a nice note that offers a full lifetime warranty if you are unhappy with it. It is also says it is BPA free, non-toxic, and eco-friendly, and 10 cents of every bottle sold is given to poor, drought affected areas. I’m happy!!!

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.

I am enjoying my new tumbler. The color is pretty, the capacity allows me to drink more water, easy to wash and I like the rubber base.
