Stanley Classic Legendary Vacuum Bottle

I've never owned a Stanley vacuum flask before, only the other major US brand. I like its classic looks and the pour through 1-piece stopper without any moving parts to disassemble and clean.There were no leaks when I filled it and turned it over. The pour through stopper works well without any splashing.I put the flask through 3 tests:1. Filled with boiling water and put in a refrigerator for about 10 hours. The water came out not boiling hot, but about as hot as drip brewed coffee.2. Filled with boiling water, but put in a chest freezer (0 - 8°F) for 11 hours. The outside of the flask was cold and frosted with ice (had some water on the outside when I put it in), but the water inside was still quite hot, almost like drip brewed coffee. I'm sure it would keep coffee hot all day during a cold 🥶 winter outing!3. Filled with cold water and several ice cubes in the morning and put in a hot car in the midsummer sun 🥵, windows rolled up (got to 104°F that day). In the early evening, noticed the ice cubes were melted, but the water was almost ice cold! I drank some, ran errands, and water was still very cold that night!I'm very impressed with the thermal performance and look forward to putting the Stanley flask to good use, winter and summer!

You can't beat this. Looks so nice and get lots of compliments, clean easily, and retains heat like you wouldn't believe. And indestructable, I have a feeling I'll havew this for the next forty years.I got this particluar one because I wanted to be able to serve coffee to anyone at a gathering, no one left out. And this delivers. Obviously it says the volume in the listing but but since I'm reviewing it may as well mention this one is HUGE.

Kept my coffee hot all day. Great product

Why did you pick this product vs others?:Very durable & keeps coffee hot almost all day.

I am a big fan of the double wall, vacuum insulated flasks ( like Hydroflask and the copycats) but regardless of their claims they are not all as efficient at maintaining the temperature as advertised.The Stanley bottles however have exceeded my expectations and are the only I have found that actually keeps my coffee or tea consistently HOT for an entire day and even overnight!!I take a big flask of hot tea or coffee with me on cold days when I have a booth outside for my business at an outdoor market. I prep the bottle by pouring some boiling water into it and giving it a few shakes ( lid on!) then letting it sit for a minute, pour it out and fill it with with a very hot beverage around 7am and it is still just as hot when I get home 11 hours later!I bought several for gifts this Christmas, and would recommend the Stanley to anyone looking for a good quality product that will actually lives up to your expectations.It is worth every penny and should last for years.The only thing I would change is the design of the handle. It is a bit awkward and can be a little tricky getting it to lay flat, but I can easily live with it.Bottom line: If you’re looking for a great insulated flask that actually keeps hot drinks Hot and cold drinks icy cold look no further!It’s the perfect size, reasonably priced and it does the job amazingly well!

Great Product, delivered expectation just not perfect.

It functions like what the manufacturer stated . Keeps hot 24 hours. IT’s durable and and it’s well made for its purpose. The size it’s ok for my use .one drawback the cover came with a little dent at the top, that’s why I am giving it a 4 stars

Cannot beat stanley for heat or cool retention. Love this blue. My last one after about 10 years stopped working to keep coffee warm. I will call gor replacement but needed one ASAP for work and loved this color so splurged.it was on sale. Can't beat stanly been using brand for more than 25 years
