- Hi, I'm Parris, and after discovering the Mighty Mug
and its amazing no tip technology,
I found out that the Red Copper mug
combines that no tip technology
with an amazing interior coating that's non stick.
After doing those reviews, one of our viewers here
asked me if I couldn't try out the Rocky Mountain tumbler.
Now, I was a little disappointed to find out
that it does tip over, but it supposedly has
the most amazing insulation, it can keep
cold drinks cold for 24 hours, hot drinks hot for 12 hours.
Let's test this out, see how they all compare.

♫ Epic review guys
- I think when people come to visit
they can always be assured I will have a mug for them.
I expect I'm going to have a dozen of them
before I'm done with reviewing mugs.
The Rocky Mountain tumbler goes for about 20 dollars.
I picked this up at Bed, Bath and Beyond today.
It's been on sale for awhile, so you can find it
at different stores and online.
I'll put a link to it down below this video.
This is very heavy, very substantial feeling
compared to the other two mugs.
It's also very spacious, holding 30 ounces of drink.
What I was surprised by is that the lid to it is clear,
and I would think it would lose a lot of heat and cold
through this, but this is so strongly insulated
that this part, I guess doesn't matter too much.
The Might Mug is still my favorite.
This clear, plastic tumbler is just great
for iced tea, my favorite drink.
It doesn't keep it as cold as long
as the Red Copper mug did, but I still like this best,
especially with the straw.
But a better head-to-head comparison, I think,
is the Rocky Mountain tumbler against the Red Copper mug.
This is really designed for hot drinks
and taking them in your car.
It doesn't have a straw and it is amazing
at keeping the drinks hot.
However, if you like a lot of whatever it is
that you're drinking, this i think is about
an 18 to 20 ounces capacity, and this one's about 30.
The thing that strikes me first holding both of them
is how heavy this one is.
This is made of steel, and even though this
is called Red Copper, and there may be some
in that non stick lining inside,
it really feels like it's made out of aluminum.
Another good thing to know for taking these in your car
is even though this has a larger capacity
and is very large here in the top half,
the bottom of both of these is nearly
exactly the same size.
The Red Copper mug, with this lid portion snapped closed,
is supposed to be pretty good about not leaking.
It has a screw-on top, and I actually like this better,
because when I first tried to open this,
I was afraid I was going to break the plastic on it.
There's a rubber ring seal inside of it,
let me open it up and show you,
that really holds it on.
I guess with 30 ounces, you don't have to open it
and refill it too many times during the day,
but this seal really holds on snugly,
which will keep it from spilling,
but it's a little bit of a chore to open it up.
There's not much that comes with this,
but what explanation do you need for a mug?
Do not put it in the dishwasher, but hand washing is fine.
This can go in the upper rack of the dishwasher.
And then they include a sticker.
This is different, a peel-off sticker
to put on this to write your name
so it won't be confused with all the other
Rocky Mountain tumblers that invariably
will be wherever you go.
And the technology that keeps your drinks
hot or cold in the Rocky Mountain tumbler
is Thermotech vacuum insulation,
and it does say it's double wall vacuum insulated.
So basically, the outside and the inside
have a gap in between that the air's been pumped out of,
and that's a vacuum, and that helps to keep
the heat and the cold in.
This is very similar.
I can tell that there's a space
between the outer and inner portions of it.
So, it only seems fair to compare these two
head to head and fortunately, I have from a previous review
an infrared thermometer, so once I get them set up,
I'll be able to take the temperature,
come back in 12 hours, remove the lids,
and see what's really going on inside.
I've put 10 identical sized ice cubes
into each of these.
I'm going to seal them up, come back in 12 hours,
see how much they've melted and see what the temperature is.
It's the next day, it's been 14 to 15 hours,
and I'm now going to see how much ice is left
in each of these and compare their temperatures.
Now, I did try out my infrared thermometer
on the surface of each.
The temperature in the house has been the same.
The thermostat's been set at 70
and it's really not very cold out.
The exterior of the Red Copper mug is 74
pretty much all over, 74 degrees Fahrenheit,
and the Rocky Mountain tumbler is showing
oh, hm, 71 near the top, 78 in the middle,
73 at the bottom, so there's something going on here
with the distribution of the insulative qualities.
Now there's a solid plastic piece on each one
so I'm going to compare the temperature there.
I assume that's where most of the
temperature exchange is going on.
This is 63 degrees on the top, 63 degrees, interesting.
This, however, is all solid plastic
you can't see through, this one,
because it's see through, I think I just have the feeling
that it's probably letting more of the cold out.
Alright, going to open them both up,
see how much ice is left.
There should be lots of ice left,
especially with the claim this is making
that keeps your drinks ice cold
for up to 24 hours, so your last sip
is as refreshing as your first.
Okay, let's start with this one.
If you ever have to, if you put like coffee
or something in this and you have to add sugar,
I guess you can slide it in there,
but if you have to keep taking this top on and off
to interact with the contents, it's kind of a pain.
Okay, there's still ice in here
and there's water in here.
I'll drain off the water and show you
how much ice there is.
This is going to be cold.
(water pouring)
Looks like about half the ice is gone,
or a little more I would say.
(rattling)
I hear water and ice in the Red Copper mug.
More ice here, I think.
Or maybe it's just the shape of this,
but let me pour the water out.
(water pouring)
Seems to be about the same amount of water.
Okay, I'm going to put the ice in my hand
so we can have a direct comparison.
Oh, this is going to be cold, okay.
That's how much ice is left in the Red Copper mug.
Looks like six or seven ice cubes.
Rocky Mountain tumbler.
Maybe a tiny bit less.
So, it seems the insulation technology
they're using here, the Thermotech,
something very similar is being used in this one
with pretty similar results.
The one advantage of this, though,
is how hard it is to tip over.
Next step, how well will they hold in the heat
of a hot drink.
I've rinsed out both of the mugs
with room temperature water so they're not
at a disadvantage by being colder inside.
This one is 69.5, this one is 69.9,
so about the same temperature inside,
and I'm going to fill them both with hot water.
I realized thinking about, should I put,
since this holds a lesser amount,
that same lesser amount into this one,
or is it fair if I fill this one all the way up
because there's the latent heat of the mass
of the water in each of them.
In other words, this one's going to end up
with a bigger reservoir of heat
and so it may keep it warm longer,
but since that's how people are going to use it,
it seems only fair to do that.
Maybe it would have been more accurate
to fill them both with ice, but there's no sense
crying over spilled milk, which I'll never have
to worry about with this one.
Always reach for Hamilton Beach.
Okay, let's fill this up to about an inch from the top.
(water pouring)
Hope I have some water left for the other one,
30 ounces is a lot.
Okay, there we go.
Also to an inch from the top.
It's so foggy in there, I can't see.
(water pouring)
Good.
They're both filled to about this much from the top.
Put the lids on.
I'll be back in about six hours.
Alright, it's six and a half hours later,
let's see how well they've retained the heat.
First the Rocky Mountain tumbler, on the outside
is about 75 degrees, still low 80s at the top.
Up here showing 87.
77.
78, 80.
And 98.
I'm worried that ...
(clanging)
Whoa.
It doesn't stick any more.
The metal expanded from the heat
and so it no longer seals on the ring.
I haven't done anything to it,
but it no longer fits.
That's in the right place.
That's all I can think is that the heat
caused the metal to expand, and so it no longer
formed a tight seal, whereas the Red Copper mug
because it screws on, even if there's
a little variation there, it's still pretty tight.
I don't know if they all do that,
I would certainly hope not.
Maybe I got one that's a little defective in some way.
Temperature inside, going to measure it
just about where the water touches the edge.
111.
Yeah, that's pretty good, 111, 112.
116.
So, even with a loose lid, it did manage to keep
the liquid inside warmer.
Let's do a subjective test here.
Ow.
Not as much ow.
Okay, this is a little bit warmer than this.
That does make sense, though.
Also because there's more volume of water in here,
so there was more heat content to start with.
But, all of that really doesn't matter
if you have your hot coffee in here
for a couple of hours and then the lids loosens up,
or rather, the container loosens up
and so the lid is no longer snug.
I can't believe that.
And it's not just a little loose, it's really loose.
Hm, I'm going to take this, dump the hot water out,
put ice in it, put the lid back on, see what happens.
Alright, I rinsed this out with room temperature water,
filled it up about two thirds with water,
put ice in it, stirred it around a little,
this has completely cooled down,
the lid still no longer fits, so I'm thinking,
alright, it can't be this, it has to be this,
and I'm looking at it and it seems
a little bit out of round.
Let me show you.
Something just seems a little bit off
and after looking at it for 30 seconds,
I finally realized this piece here
that holds the seal on the outside
has actually bent inwards.
In other words, it has melted, or at least softened up
to the point where it could fold in,
not as much here, but definitely on this side
it's folded in so it no longer pushes out
against the inside of the tumbler
and holds it in place.
Just for comparison, the inside of the Red Copper mug,
you can see it has the seal here,
and then this is the part that pushes out with the threads
against the outside of it, and I don't see
that anything has changed here.
It still fits perfectly fine and screws in perfectly fine,
and the water in both was exactly the same temperature.
So, belatedly, I looked on Amazon
for reviews of the Rocky Mountain tumbler
and found it has an average of two stars.
63% of the ratings are for one star.
Comments about it leaks, the lid leaks,
my coffee spilled everywhere, doesn't keep things hot,
the lid leaks.
Well, of course it leaks, now it didn't leak at first,
but if it's going to melt from having a hot drink in here,
that's just pretty crazy.
So, it's possible this one was particularly defective,
but it seems like some other people
are having issues as well, so if this were a challenge
between the two of these, the Red Copper mug
with its no spill, no tip feature,
I gotta go with this one.
