Kapoo 17OZ Double Wall Insulate Stainless Steel Water Vacuum Bottle, Suitable for Both Hot & Cold Drinks, Perfect for Outdoor Sports Camping Hiking Cycling, Portable, Compact and Durable(500 ML)

This is a really great knock off! for the price, you wont get better for a standard water bottle. I am using it for just cold plain water, and if you leave it in your purse with the lid on it will get a touch mildewy smell. I have rectified this by just putting water from the "hot" tap of the water cooler at work in it to the brim and letting it sit for a bit and then air drying. certainly recommend!

Keeps drinks really cold for hours.
