Is tumbler really vacuum insulated or just double walled ? The felt sticker at bottom seems to have hole in the center.

I do love the tumblers ~ however ~ they do NOT keep beverages hot or cold for any additional time! Additionally ~ lipstick is extremely difficult to remove!

Mine has a button on the cover that pushes in to drink, so I can't really say. Loose parts in the stainless? Does not sound good. Are you sure you are referring to the 'vacuum' stainless? They do have other versions.

It is double wall insulated but stainless steel inside and out. I think it could go in the dishwasher, but it only will have ice (water) in it so why would it need to? I just give it it a good wipe down and dry it off. I also would not want to mess with the seal, but it looks very well constructed.

It's a felt like material on one side and plastic on the other side. The felt gives it a little insulation so you can use this side out of the freezer. Than when it heats up a little you can turn it over since the plastic side stays cold longer. Great product.

I haven't dropped my mug, yet....my husband says he thinks it is stainless covered with some type of epoxy, something that is insulating. I tried scratching it....it will scratch...I used a bottle opener....but it does not look as if it will chip...hope this was helpful....I recommend this thermos cup.

The lid closes so that it is quite, but not "fail safe" leakless, and after twisting the lid it is easy and convenient to sipI bought 4 of these, because I love them so much. But, the last order it had some hole somewhere and water somehowcollected inside the vacuum center and sloshes around unappetizingly, and keeps the cup from keeping hot drinksfrom staying hot. Ihope this was only a rarity. But, just telling the truth.

The lid is not insulated, only plastic, but my husband also works in very hot weather, when using the cold packs (plastic) this is an amazing cooler, as my husband works construction, and this is big enough for a couple meals and extra drinks for the job site, I would highly recommend it. We use it when we go to the zoo etc. with the kids too! Works Great!

The lid is glass. It has a flexible rubber (or silicone?) double-flanged seal that holds it in place. That's the black strip you see at the top. You don't screw the lid on - you just press it down and the double flange holds on to the inside of the tumbler. Lift up to remove. Easy and effective - I've had no spills ever.

It is not insulated. It is a clear bag. I use it with an ice pack and it works fine.

There is a small hole at the top. Must not be pictured but there is a hole. Plus you don't need that much ice that it would overflow as it melts.

The tumbler is clear. You cannot personalize with a paper between the double wall.

Engineer here. It'll serve almost no purpose other than heating the outside glass shell. The purpose of the double-walled design is the void between the two layers is a super insulation layer. Note - I'd recommend a stainless steel thermos coffee cup over this POS all day long!

No, it is made of double-walled plastic to act as an insulator. Hope this helped?

I'm not an engineer but I am 99% sure it is double wall. It is not insulated, but holds heat pretty well. It is a nice sturdy press and I like it very much.

There is no lining in the tumbler - Its the same stainless steel interior and exterior -

The cup has a stainless steel liner with the molded plastic outer shell. You won't burn your hands from the cup. For only $9.00 or so, you're not going to get a vacuum insulated cup. The lid has a sliding cover (to allow you to drink), that's what keeps the heat in if you're drinking coffee.

No...you need double side walled, vaccuum seal for that...i send my daughter to school with a thermos for that
