Tumbler 30 OZ/850ML, Insulated Coffee Cup with Lid and Straw, Double Walled Vacuum Stainless Steel Mug, Reusable Travel Flask for Hot and Cold Drink, Ice Smoothie, BPA Free

This product is advertised as being able to keep cold drinks cold for 8 - 10 hours & hot drinks hot for 6 - 8 hours. Drinks include beer, cola, milk, coffee & juice (see relevant image). However, when it arrived, the packaging it came in clearly states, "Do not fill for long periods of time with milk, dairy products, juices, carbonated drinks, which can be corrosive to metal (see relevant image).I would class 6 hours as a "long period of time" for a drink & if I had known this beforehand, I would not have purchased this product.Thankfully, Amazon makes it relatively simple to return products with a full refund (if the item is as you received it upon delivery).Just a heads up 🫠

These are so dangerous. I had mine two months and after multiple burns and big spillages I've thrown it away. The lid is not air tight and comes off easy which has caused me burns and spilling full cups of liquid. The lid isn't even screwed on you just push it in and there's no suction or anything to keep the lid secure very bad design I wouldn't recommend and I'd never buy again.

I chuck a load of ice in pour on my ice cold water and the ice is melted and the water is just like its come from the tap within 2hours! Mine must be broke! Looking forward to the winter months will try it out for my hot drinks hopefully i can get to work without it going cold 😂

The travel mug looked great and with 2 lids, great. No straw in the box but wasn't worried until... I tried the mug with my morning coffee and the lid just would not seal and popped off. Fortunately the spillage that occurred missed my person but there could have been a serious scalding incident. Cup was returned.

This product is not suitable for hot drinks - the lid pops off because of the pressure. Dangerous for anyone using it as a travel cup. This was returned

The lid is not seal and it leaks. 100 degrees water was at best in lukewarm temperature after 1 hour in this thing. Absolutely useless. Thanks for nothing

Lids not very secureThe mouth hole is too deep so you get coffee everywhereDon't waste money on this

I have a few insulated tumblers but this is by far the biggest one that I have as it is a whopping 30oz capacity and is nearly 20cm tall. The tumbler arrived neatly boxed and came with a flip lid, a straw lid and a metal straw with a silicone tip. The colour I chose is a really nice shade of turquoise.The tumbler is designed to keep hot drinks for up to six hours and cold drinks cold for up to ten hours. The two lids offer different options depending if you want to use a straw or not. I tend to use a straw and find that the silicone where you put the straw is almost too tight to get the straw through which makes it sometimes a bit problematic but it also doesn’t exactly fit the hole so when you pull the straw out you end up taking the silicone with you. It is only a small thing, but when you use the tumbler regularly it’s quite annoying. I also find that sometimes the lid does not always stay completely shut if you have a carbonated drink in it and the tumbler is over three quarters full. You cannot put this tumbler in the dishwasher, but that’s common with most of these items. It is not really a problem though, as it’s easy to keep clean.*Updated* After only using this for a couple of weeks it has now turned into a fountain! Every time I place a can of drink in it (which doesn’t even half fill it) I put the lid on and it comes out of the straw. As mentioned above the lid was never a great fit but in a short time it seems to have got worse. It has only been washed by hand and not dropped so no idea why it has become so bad but it is now heading for the bin and therefore I have reduced the score to one star (because I can’t give it zero!).

I got this so I'd have a reusable cup for my daily tea at Starbucks. This works really well, I can get the largest size and it stays nice and cold for the entire time I'm drinking it. Very easy to clean. Would purchase again

Der Becher ist einfach super gut 👍 👍

When an a-hole 5 fingered my father's day gifted expensive one I took a chance on one a1/4 of the price- and love it- holds ice as well and came with 2 lids & ss straw- love it

Der Becher ist super und die Farbe der Hammer. Mir persönlich war der Becher zu dick zum ordentlichen Festhalten. Ging daher leider zurück. Preis- Leistungsverhältnis ist sehr gut.

Agréablement surprise par rapport à quelques commentaires négatifs. Garde bien chaud et ne coule pas. je recommande vraiment
