Kujaku Sports Bottle Product Review – Keeping my drinks hot or cold

Kujaku Sports Water Bottle

I been frustrated with water bottles for the past years that made me decide not to use anymore. There are times that I wanted hot water and sometimes cold water depending on the weather in doing that I will be needing 2 separate bottles. But one frustration is that they can’t keep my beverages temperature longer. Some of the water bottle like plastic would have this plastic taste. For the aluminum and stainless steel bottles has this after metallic taste that made me worry for health hazard.

I heard of Kujaku Sports bottle and got it a try. I talked to some of my friends that tried Kujaku but the feedback they are frustrated that the brand does not do its job. I been using my Kajuku Sports Bottle AMJ-R80 for almost a month now. I was pretty surprised with it and impressed that made me love it so much. With some research I learned that Kajuku use surgical stainless steel #304 insuring there would be no health hazard in using it. All of their water bottle is insulated

At first try I tried to place hot water in it and see how long it would take the bottle to retain the heat of the water. After 24 hours upon opening the sports bottle I still have hot water that I can even stir up a cup of coffee. Kajaku sports bottle is vacuum insulated double layer bottle keeping hot or cold beverage longer. Also you won’t even feel the bottle body to be hot or cold to the touch.

I often used my Kajaku sports bottle for ice-cold water and I bring it anywhere while traveling, driving during stuck in traffic and at bed time. It can fit one tray ice cubes and it would last the whole day your beverage being cold. I would advice that when putting water with your ice make sure your water is cold or else your ice would melt faster.
