SiggInsulated Flask - Thermo Flask Hot & Cold ONE Light - With Fruit Filter - Leakproof - BPA-Free - 18/8 Stainless Steel - 0.55L

Brilliant ice remains frozen for 24 hrs!!!Love this flash easy to clean and drink from open spout great brand

Great flask and the only one I could find that is certified for sparkling drinks/water. No leaks, well balanced and well made. easy to open and close whilst driving. It does open with a "pop" when sparkling water is used but makes you feel like you are opening a bottle of Champagne!

Sigg bottles are great. Not sure if there is a slightly bigger one.

Keeps hot drinks hot for a very long time. I love that you can open it with just one hand pushen the button

Does as promised re keeping drinks hot or cold. Useful carry handle, one-hand flip top and nice drink spout. Recommend not leaving it empty with the top screwed on though - it gets smelly; fine if you leave the top off.

Good quality and easy to use.

The media could not be loaded. Totally disappointed. I had a great SIGG bottle before, the basic one with a round cap, and thought this would be the same. The good thing about this bottle is that it has a beautiful design, retains the water well, and keeps the content cold or warm. On the other hand, the cap design and functionality are terrible. If you are in a silent room watching a presentation and open or close it, it will make a huge CLICK, unless you handle it very carefully. The hole where you drink the water is small and also noisy (you hear a lot of glub, glub, glub). In a world where we should be drinking at least 2 liters of water per day, this bottle will make you drink less than 550ml. My water always tastes like plastic, no more how many times or how I clean it. Paid more, expecting an intelligent design, but got the worst bottle I ever had and a bad value for money. I am still using the plastic bottle that came with orange juice at home to drink water and I carry this when I go out because it "looks nice".

Excellent!
