So you'll see some things about how it fits in a car cup holder (Lots of others do too) or how one survived a fire (This is just how insulated bottles like that tend to work) and those are all... good enough... but they're not why there's so much hype. The Hype has been carefully engineered. The head of the company is a Marketing guy, and he basically imported Sneaker culture into a new industry. Stanley Cups are released on a limited basis, with partnerships producing only limited supplies. It's induced scarcity and marketing, people are rushing to get one because if they don't rush, there won't be any more, and that makes more people want to rush to get one.
It's just an insulated cup that is intentionally hard to find sometimes. That's all.
I got my last insulated cup from a hardware store. $7 and change.
No branding at all, just "insulated stainless steel cup"
It's the best cup I've ever had, and I can't even tell people what to look for because the packaging was generic black text on white cardboard, around the base of the cup for stability. That's it.
I forgot I made some hot chocolate one night last week, and when I woke up in the morning, all I had to do was stir it to get the chocolate mixed up well, and it was still warm. Not hot mind you, but warm enough to get me to work. I'd say hot time is 2-4 hours. 5-6 if you slide the lid closed.
Now I want to run some temperature tests but I don't have any temperature sensor and logging programs to do them though.
It's kept ice for 24 hours. I dumped it so no idea how long it CAN hold ice.
Also I have no idea how these times compare to the expensive brands, since I've never owned one. They could be sub-par. But they're infinitely better than the ceramic mugs or Styrofoam/plastic insulated cups I used before, so.... Yeah. They've got that going for them. Which is nice.
Do you know what hardware store? I got a Thermos brand thermos for Christmas but it has a weird screw style stopper that makes it a hassle to drink from or open up, would very much like a solid insulated cup/bottle.
