To calculate the overall star rating and percentage breakdown by star, we don’t 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.
Bad lid design and you can’t push the tab flat. There is a loose piece of metal in between the walls of the cup abs it rattles around, which is super annoying during the morning cup of coffee. I’ve messaged the seller and had no response.
Nice size but does not appear to be well made. Tumbler has a seam along the length of the side of the interior. Where the side is connected to the bottom, there appears to be some sort of material (weld, glue?) which I hesitate to have in contact with my beverages. Finally, the bottom exterior of the tumbler appears to have a thin circle of metal in the center. This was both placed slightly off center and does not represent the picture in the item listing. I have significant doubts whether this will be as durable as advertised.
We have numerous insulated containers, but I wanted a small one that I could fill with wine and super-chill in the freezer before drinking. It's great for that, but I wish the lid was more secure -- it doesn't like to seal well.
