To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Does NOT perform as promised. Put in cold water and could immediately feel the coldness on the outside of the flask (what insulation?!) & within 2-3 hrs, water was close to room temperature...very very disappointing... EDITING this review because it turns out the 1st one I got was faulty and Amazon quickly refunded me and I got a 2nd (32oz) & (recently) a 3rd 64oz one and they are perfectly fine! Initially wrote to Ironflask but they explained I had to reach out to Amazon for my refund since I bought it off Amazon. All round amazing service from both Ironflask & Amazon.sg. Very happy with my 2 recent purchases. Highly recommend!
Fantastic for keeping drinks cold, ice stays in it for above 24 hrs, I use mine for work in a warm environment so fill it half with ice and half with water and keep topping it up with water, just make sure you keep the lid tight to keep the cold in. Brilliant product and fantastic colour
Great bottle.. and when on special is a very good value item. It is near perfect... except one minor flaw. And I'm more then likely just unlucky. But my bottle has a small piece of steel trapped in between the dual walls of the bottle and it rattles around. Absolutely nothing impacting the function of the bottle but unfortunately quite irritating. Otherwise a great bottle!
