Questions & Answers

Can you tell me what type of material is inside Is stainless steel a good material? Is it glass? What is plastic?

one part of the sleeve that is black has a rubber band mounted on the top which is removable and has a small lip on the top to align with the opening on the side. Both the inside and outside of the sleeve are stainless steel. You can use it as either a cup or an insulator for paper cups. I use one with a plastic cup inside, it insulates very well, I've had it for over a decade. I have no problems with it and it still works just as well as when it was

Are these suitable for Dunkin' ice Is it possible to use these plastic cups?

The McDonald's beverage cleaner is used on all drinks - hot and cold McDonald's offers medium and large cold and Burger King offers medium and large. The only thing that won't fit are the very large Burger King plastic cold drink cups, which will sit higher or lower depending on the order. I think this will be really useful. It really keeps coffee warm for longer, certainly for My wife and I each bought one for our cars.

Could anyone tell me how this works with tall, grande, and venti coffee cups from Starbucks?

The mug fits all Starbucks cups, all shapes and Due to a lip on the Starbucks cup, tall and grande sized cups stay in place. In the venti cup, the lid comes above the black of the insulator, keeping the coffee hot much longer than at the table Keeping a venti hot for three hours is no problem for me.

Hot coffee is kept hot with this! I've used this in my car cup holder and have been happy with the way it fits my venti size Starbuck Pike Place drink and remains drinkable for three hours
5/5

It fits in my car cup holder comfortably and the rubber like ring is easy to hold. had used my first one every working day for 22 years and it was like new, but somehow it was lost when I moved into retirement. A new one had to be purchased.

I find these to be very effective
5/5

A typical paper coffee cup held within one of these stainless insulated cups will hold about 20 ounces of coffee. Their function in keeping drinks hot or cold is excellent. Cold drinks sold at coffee shops do not fit well into these cups, however, you can transfer the cold drink to one of their 20oz paper cups, and they will work fine.

You should keep coffee hot at all times
5/5

Coffee stays hot for at least four hours. I have used this various times over the Start by boiling water, then use a 20-ounce paper cup and fill it until the bottom of the cup is reached. This cup holder fits in the cup holder of most cars.

After a little work, it is working as it should be
4/5

Two of the four ordered arrived. Of the four, the first was fine. The second was dented and The package I got was round enough for me to use, but it could be better packaged. Our lattes remain lovely and warm now that both devices are working.

It was not what I expected, and I did not enjoy it. The feeling of being robbed is overwhelming.
