Pros & Cons
Pros
These little things are gems. My friends joke that i have an amazon forklift, not a shopping cart. They make great gifts and are really a conversation starter.
The coffee doesn't have to be reheated. At that time, they could be purchased in a set with a stainless steel insulated mug for abut $100. They work fantastically several years and several hundred mugs of coffee later.
The thermos is almost totally spillproof when the valve is closed. It has already edged out all my other travel mugs. The mug does such a good job of retaining the heat in the coffee.
The same day at 9:00 a. M. Expanding the window of comfortably hot drinking temperature. As i do transport for our shelter and other rescue groups, on the road i want my coffee hot.
Cons
Stainless steel beans are much larger in size than the real coffee bean. When the joulies are cooler than 140°f, the wax inside is frozen (solid). When that happens, the wax starts to freeze. Coffee keeps getting cold forcing me to microwave it every ... Read More
After many efforts to have at least a low satisfactory one, i feel the two five-star reviews are bases on something other than facts.
My biggest quip is that they don't even come close to doing what the inventors claimed on the shark tank. I cannot imagine how the sharks even got involved with this product - it is all hype and zero delivery.
Highlights
Quality
I have had it for 4 years and it still works great
They bring the hot liquid down to temperature very quickly and hold it there for quite a long time
They are much less effective in a cup that absorbs heat without a lid like a ceramic coffee cup
If you use a ceramic mug then joulies will be not good at all the best container by far for using joulies is an insulating thermos
Price
Value directly linked to the quality of your thermos
A bit expensive but only pay once
They are pricey but absolutely worth every cent
Shipping
I had tried to ordered them just after the kickstarter but they only offered priority shipping to canada so it wasnt worth it
And got stuck in traffic at 630 a
On days i get busy and havent finished it by lunch the remaining amount is still warm and enjoyable
Competitiveness
I use a very simple insulated metal thermos from starbucks and it works great with joulies
My friends joke that i have an amazon forklift not a shopping cart but heres one time where the company website is better
Later when the temperature of the coffee is at or a bit lower than that of the joulies the joulies release their thermal energy... Read More

Im surprised at all of the negative reviews since the physics involved is rather simple
Posted by a reviewer on Amazon
If you use an open cup or a travel mug that is not well insulated they will only maintain the temperature based on how quickly that mug loses temperature
Posted by a reviewer on Amazon
So with an open cup they arent going to be much help at all
