Umite ChefStainless Steel Water Bottle with Straw, 64 OZ Wide Mouth Vacuum Insulated Sports Water Thermos Bottle with Leak-proof Wide Handle Straw Lid, Hot Cold, Double Walled Flask Thermos Mug(Blue)

Confession Umite Chef is by far my favorite cup/tumbler maker. I've tried many different brands including Yeti & Stanley. In my opinion Umite Chef tumblers are better BY FAR.This was the first one I bought with the built in flip up straw. Just as the others it works great and keeps my drinks cold. I can leave it in my truck in the sun all day and come out to a cold drink at the end of the day. Crazy but I highly recommend 👍👍

This bottle is great. Just with the mouth piece was wider.

it was an amazing purchase! i do recommend!

This was a little bigger and heavier than I anticipated.

When I got this I first noticed "Leak Proof and Sweat Proof" on the side of the box so I decided I had to test this.I filled it up with ice and was able to have it sit upside down, supported by its shoulder, for over 2 hours and I can say that it does not leak or sweat.I then decided to test the 24 hours cold and 12 hours hot.I started by filling it with 14 standard ice cubes and cold tap water. I checked it after 4 hours and it was 32 degrees (F). I checked it every 2 hours and after 6 hours it was 33 degrees and it appeared the ice was about half size. At about 10 hours still 33 degrees and the ice is about a third of the size. After 24 hours it is 35 degrees and the ice is almost gone. At 28 hours the ice is gone and it is 36 degrees. At 32 hours it is 40 degrees, At 38 hours 44 degrees, at 48 hours 50 degrees and at 60 hours 55 degrees.I then took the water and put it in my electric kettle which got it to 205 degrees. After 12 hours it got down to 148 degrees, 20 hours was 125 degrees and 36 was 101 degrees.I would say that the claims of cold for 24 and hot for 12 are pretty accurate, though I kept it in the same spot the whole time and it was about 70 degrees in the room it was sitting.During both tests the container didn't get too hot or too cold to the touch, you could tell it was a little warm or cold but still comfortable, the only problem area was the lid which did get fairly hot, I probably wouldn't drink any hot beverage from it.If you have ice in the container I noticed that it kept knocking off the straw, but with no ice I didn't see that problem and if you shook the lid the straw would stay on, unless you really shook it.TL;DR This is a great thermos and the claims of 24 hours cold and 12 hours hot are accurate as well as being leak proof and sweat proof.

It is so pretty and worth the buy. It is kinda heavy though before anything is put inside.

It is a great insulator. Like the ice can last for almost two days depending on how much you put in it. The only problem is that it is a bit too big. The size makes it difficult to fill up from the refrigerator water dispenser and the water cooler at work. Might work better if you had a water filter on the kitchen sink to fill it with.

Every morning I grab my 64oz water jug fill it up and take it to work and have water all 8 hours.

Five stars for build quality, four stars for insulation. It definitely does the job but the bottle gets cold to the touch meaning some of the energy is definitely getting in/escaping. Overall I am happy with my purchase because I knew I wasn't going to get perfection at this price, but if you are looking for fantastic insulation, look elsewhere

Amazing value. Great bottle! Hold lots of water and Keeps it cold for long. Comes with extra straw and brush

I am from Australia and I read the reviews and was worried about the ones saying it came damaged. Mine came a month early and was in perfect condition! 100% recommend!
