Mountain Source 27oz Thermos Stainless Steel BPA-free Insulated Water Bottle (Black)

This is an amazing thermos. First of all, its not too heavy, it comes with a flip top (sports like spout) and it has a little lever that when turned is leak free. It comes with a cup that turns it into a thermos!.What I really like is that its not wide like the typical thermos but it holds a lot of liquid. it fits very easily into a backpack or a big purse. Now the best part is how cold it keeps liquids. I live in Florida and I received this when temps were low 90s. Im on a rowing team and so I had this on the bottom of the boat in the hot sun for 3 hours and my ice cubes didn't melt. I fill it with ice cubes and water and I get a full 2 days of icy cold water sitting in the direct sun. There are lots of other thermos bottles on the market but I'm telling you this is the only one I will ever want. I can't wait to try hot coffee in it ! There is nothing negative about it.

I purchased 1 of each colors and the only thing I wish is if there was a brushed stainless or polished chrome finish. The placement of the carrying loop is positioned nicely but I would have likes a little thicker at the joint. Also the bottom cushion is nice but makes the bottle a fraction to wide at the base to fit in some car cup holder.All in all it is very efficient in keeping water cool. I added 2 ice cubes in the morning and even after the bottle was in the car the ice lasted till past 1400.

I bought this to keep my water nice and cool throughout my work day and this exceeded my expectations. My water stayed surprisingly cold for hours! It felt like everytime I drank from it the water got cooler and cooler. Very satisfied,Very happy with it.Nice sleek color, matte for a good grip and the top little handle comes in handy.When you first get the water bottle I washed it 2 times because it came with an odor but went away quickly and no problems now! Would purchase again!

-Keeps water cold for a Loooooooong time....we had ice in it for like 2 days without melting-hold a LOT of liquid-the flip top cap/lock is well designedBuuuuuuuuuuutThat same flip top cap shattered when my son knocked the bottle on the tile floor....it was $14, i'd gladly pay $20 and get a much better grade of plastic or even aluminum

Nice water bottle. I work 9 hour shifts and it keeps ice and drink cold. I like the fact that I can switch up the tops depending on hot or cold drinks. Its a bit odd drinking from the bottle with the top flipped up but not a big deal. So far, this is a great product. No leaks and keeps my drinks cold.

While I like the larger size of this bottle, the bottom plastic piece broke the first time my daughter took it to school. Admittedly, she did drop it, but I would have expected it to be sturdier. Also it doesn't keep her ice water as cold as a comparable Thermos brand water bottle. The water bottle also didn't fit into my car's cup holders, so maybe it was a good thing that the plastic piece broke because now it fits, lol!

This thermos does not work as well as advertised. It doesn't last well with ice, and it sweats. I put it in my bag and left it there for less than 3 hours and the bag was wet and the thermos was sweaty. I was thoroughly unimpressed. I don't recommend it if you want to keep your cold beverages cold. Maybe it fares better for hot beverages...

The description of this bottle says its leakproof.. guess what?? it isnt..!! 3 days of use and this bottle is already leaking water through the cap (it wet all of my books).. at first I thought I did not close it well, so I open it and close it 3 times and it keeps leaking.. I'll see if I can upload a video later showing you the problem.. but yeah, what a waste of money.. oh and yeah if it leaks it means air can get in and out of the bottle so it wont keep my water cold anymore.
