This is BUBBA. He is my constant companion.This Bubba Keg is absolutely the most amazing insulated mug I have ever come across and believe me, I've been through a lot of them. I wore out a half dozen of the plastic insulated mugs before I discoverd the Bubba Keg.
The Bubba Keg is tough which is a major plus with me, because I have been known to set a mug on the JEEP bumper and absent mindedly drive off. Do that with a plastic mug and it's usually toast, but the Bubba has taken several spills with no damage. I use it at work, in the yard, in the boat, in the car. It has a nice wide (fat) footprint so it's not easily tipped over. It's so stable that I usually don't bother using the lid, I like to make full contact with my ice water and drinking through a hole is not my preferred method.
The really amazing thing about the Bubba Keg is how long it can keep cold things cold. (I imagine it is equally good at keeping hot things hot, but I only use mine for cold drinks)
The Bubba Keg company claims the 52 ounce Bubba can keep cold things cold for 12 hours and they are not exaggerating. I've left my Bubba full of ice and water in an enclosed car for an entire workday (On a Florida summer day) and still had ice and ice cold water in it when my 8 hour day was over. Amazing.
The only drawback (to nonBubba owners) may be it's enormous volume. When I fill it with ice tea, it drains the pitcher which requires my son to make more ... making the family ice tea is one of his kitchen duties.
The Bubba Keg ... don't leave home without it.
