About IRON FLASK Sports Water Bottle - 40 Oz
Overall Feedback:
95% positive
94% highlighted the mouth opening size
The wide mouth of my water bottle is great for cleaning and putting ice in.
92% liked the material durability
I am impressed with the durability of my water bottle. It has remained intact despite enduring countless drops, bumps, and adventures. There are no leaks or cracks, even after years of use.
92% found it leak-proof
The bottle is leak proof and sweat proof, making it easy to carry in a backpack without worrying about getting belongings wet.
91% were impressed with the insulation quality, but 9% weren't
After 4 hours of use, the bottle still had ice, indicating good insulation quality.
The insulation quality of the bottle is insane. Even when left on the counter with just ice overnight, the ice was still solid the next afternoon unless it was left in direct sunlight.
I noticed that the flask was not insulated properly. The water inside the flask became close to room temperature within 2-3 hours and I could feel the coldness on the outside. I am disappointed with the product's performance.
91% found the grip comfortable. while 9% raised concerns
The only drawback is that the cup doesn't have a rubber bottom, which would have been nice for grip and to avoid clinking when set down.
I find the 64oz water bottle difficult to grip and drink with one hand due to its size, but the surface provides extra grip when it's not wet.
