Aside from the spill proof lid this 35 oz MUV Coffee Mug I purchased is complete garbage. I'm an avid coffee drinker and I like my coffee hot. This mug doesn't have a snowballs chance of keeping it that way.

I filled the mug. Waited about 15 minutes then took a sip of the coffee. Still hot. So with my everyday trusty 20 oz cheap mug also filled I started my testing of the Brumate 35 oz mug.

45 minutes later I take another sip of the coffee from the Brumate and notice that even with an airtight lid the liquid (coffee) had cooled. So, just an hour into testing the claims of the company that it will keep liquids HOT for 6 hours and COLD for 24+ was quickly fading.

So, thirty minutes later I checked it again. The liquid was warm. Not a very good start for a mug that the company clearly states will stay hot for 6 Hours when there is no way this liquid was going to be anywhere close to hot even in 4 hours let alone 6.

I decided to go back home and start over. I figured I'd help it out before pouring coffee into it. So, I brought some water to a slight boil then poured it into the mug. I then locked the airtight lid and left it for 30 minutes.

At the 30 minute mark I opened the lid, which was actually very warm to the touch telling me this could be a good sign. I emptied the mug of the water and poured in some very hot coffee and closed the airtight lid. I performed this process with the thought that the hot water would heat up the inside for the coffee.

This time around I will check the status of the coffee, in the mug, every hour.

Hour 1. The first couple (sometimes 3 to 4 sips when I say couple) of sips of coffee are warm but the next couple of sips are hot. I closed the airtight lid and waited another hour.

Hour 2. The first couple of sips were cool then the next couple were warm with the next few sips kind of hot. I could easy tell that the temperature was dropping.

Hour 3. Cold coffee first couple of sips the rest of it was cool to slightly warm. I knew at this point that the preheating of the mug with hot water didn't work and that by hour 4 this coffee was going to be cold.

After taxes my $50 (after taxes) 35 oz Dark Aura Brumate Mug could not do what the Brumate company claims it can do. I also purchased the 25 oz Primrose for a friend who stated that hers didn't perform well at all.

I asked her how long the liquid stayed hot and she said she did not know as she used hers for iced tea and that it wouldn't stay cold all day.

So, I tested the cold claim as well. I like unsweetened grapefruit juice. I placed the mug in my refrigerator and the grapefruit juice in the freezer. When the grapefruit juice started to get that slightly frozen slushy look, I poured it into my 35 oz Brumate mug.

I'll keep this short but the grapefruit juice was nowhere close to cold or even cool 5 hours later.

So, to sum this up, it cost me almost a $100 for two mugs that can't even come close to the claims the company says they can.

An $8 - 20 oz travel mug from Walmart literally keeps my coffee hotter longer. Yeah, it's not spill proof but ask yourself this, how often do you spill your drinks anyway?

Do yourself a huge favor and read up on and check out multiple revies on a product before making a purchase.

As for Brumate I can say that I will never purchase another product from them.
