It's certainly infuriating having scalding hot coffee spill onto your pants on your way to work in the morning. Gridlock traffic aggravates you badly enough without the screaming of the nerve endings in your legs compounding your fury. I realized I needed an upgrade with a coffee mug that didn't roll out of my cup holder and spill all over me like this. I went on a mission to find a better coffee mug and was shocked to discover how incredibly difficult it is to find a decent coffee mug without spending $50 or more. Plastic mugs break the first time you knock them off the counter. Steel mugs without insulation don't keep anything hot or cold.

Mugs with insulation fall apart in the dishwasher. Then there are the lids. I had no idea finding a lid that didn't spill usually meant complicated sliding parts that were extremely difficult to properly clean. I knew that I wasn't alone in searching for a mug that would do the simple task of providing a safe, reliable container for transporting a beverage in the car, yet so many of the options available fell short. So I resolved that once I found that special specimen that I would save everyone else the searching and provide it through the largest and most reputable online store the world has ever seen, Amazon. Cheers.
