I am extremely impressed by the quality, durability and functionality of this heavy duty water bottle. I love how it keeps my beverages super cold or hot for 12 hours with the copper infused into it. This water bottle is perfect to take on the go because I do not have to worry if it gets knocked over in my car because it is a 100 percent leak proof.  I like that it comes with two different lids so I can use it with either a straw or a flip lid. I absolutely love the size because I am not feeling like I have to constantly refill it, but I really like that it is not heavy. I love that is it corrosion resistant and BPA free. I would definitely recommend this to anyone who is looking for durable and perfect size water bottle as you will not be disappointed in this one.
