Awesome as always!!!

Honestly I have had a lot of keep cups before. The OG plastic w/ rubber grip, glass w/ cork grip, the StarWars Vader longplay. But they all had one thing in common, they kept the drink warm but never for very long. Enter the KeepCup Thermal. Not only does it look absolutely amazing with a powdercoat-esque finish, but it keeps the drink warm for much of the (working) day with no questions asked. That being said, good luck not finishing your drink before then! This is still very much a to-go cup and not an adventure cup however. The lid is only affixed to the cup via a friction fit rubber seal, and the top cap is definitely not air tight. If you've ever accidentally overfilled these with a hot drink you'll know what I mean, I do not recommend trying that though. The spill-proof claim is entirely situational as well, as a to-go mug that sits in your cup holder, you will never have an issue with it. But do not ever think you can put it in your bag and not end up having to turn in a coffee soaked report, or finding your dry clothes to have an, admittedly awesome, new coffee tie-dye. With all that being said, I don't think I would ever get anything different for my general day-to-day coffee cup needs. Everything about the cup is refined and works exactly as you would expect it. So, if you're looking for a day-to-day to-go cup, I highly recommend the KeepCup Thermal as it very easily could be the last cup you'll ever need.

The finish on the outside of the cup is nice, the lid did need to be soaked to stop it tasting awfully plastic when drunk from but that was easily resolved. Customer service was excellent as I originally ordered the wrong size (16oz is it filled completely full to the brim, perhaps that's obvious to most people), and had no problem exchanging.

It's perfect! The mug is perfectly thermal: my coffee is a hot very long time.
Washing this mug is easy!

I have several of the glass/cork non-thermal 16 oz. Keep Cups, which I enjoy, but they do dissipate heat quickly. I purchased two of these thermal Keep Cup versions and they are fantastic! They keep my coffee warm for a very extended period - exactly what I wanted from the product. It does appear that coffee which drips onto the side of the mug discolors the mug (i.e., the drip streaks show up on the material used) - this has occurred on both my pink one and my darker blue'ish one. It's not a big deal to me, though it does annoy my partner. As another commenter has noted, this is not really a "throw in your backpack" type mug, given that the cap does not screw on. True. For that, I use a Fellow Carter Move Mug (16oz) or a large Stanley Thermos. But around the house or in the car's cup holder, the Keep Cup thermal 16 oz. has been wonderful
