This mug does the job it was made for well, is easy to clean, and is very rugged. Below are some of the features and a brief but accurate performance measurement.Temperature retention:Over the course of 7 hours, the temperature of the liquid inside the mug dropped by 62 degrees F. This sounds like a lot, but if you put boiling water in it (around 200 deg. F), you will have very hot (around 130 deg. F) water to drink after a full-ish work day. This is more than most people need.To test this, I filled the bottle with 12 oz water that initially measured 191 deg. F with an instant-read thermometer and then placed the lid (in closed position) onto the mug. It was kept in a room temperature environment until the next reading, when the lid was again removed. Note that the temp. drop would have been less affected if I were able to use the 'Hot Shot' cap to take the measurement, but the instant read had to be inserted into the liquid to do so. See measurements below:0h 00min 191 deg. F2h 00min 163 deg. F4h 30min 143 deg. F6h 30min 129 deg. FThe biggest heat loss is though the threaded portion of the upper lip because it is a continuous piece of steel and, though vacuumed, provides more transmissibility to the outside air. Other mugs do a better job in this area but only by sacrificing durability. If this tradeoff is worth it to you, you won't mind much!Size/Weight:The mug measures almost exactly 3" in diameter straight down to the base with a height of 7.25". The lack of taper makes it less likely to tip over but also less likely to fit in your car's cupholder. In my Kia Optima, it barely fits in the center-console (it doesn't touch the bottom and is squeezed by the sides) but fits perfectly in the door. On my wife's Volvo XC60, it fits well in both.I should also note that it fits perfectly under our Nespresso Vertuo machine and an 8oz coffee + crema makes it just under the threaded lid. Wonderful!The mug + lid weigh 14.4 oz. When filled with 12 oz liquid and placed in a backpack, it'll be a 1 lb 10.4 oz drain on your shoulders... But it'll be durable!Cleaning/Assembly:The 'Hot Shot' lid is easy to remove and disassemble for cleaning. You just twist past two soft 'clicks' and it's out of the housing and ready to clean. It's also dishwasher safe and you can drink from any point on the lid, which are nice features.My only gripe with the lid is that you can't tell if it's opened or closed just by looking at it. I have gotten in the habit of just closing it every time so I know to open it before taking a sip. Yeti could fix this by putting a colored dot or notch on the inner/outer portions of the lid so that, when they line up, you are assured of it's position.Conclusion:Overall, I have been enjoying this mug a lot and hope this review helps you make the right decision. It's a solid performer, has great features, and looks more expensive than it is.Side note:This YETI Rambler was purchased for the sole purpose of keeping an 8oz Nespresso Coffee hot, and for this it is perfect. If you don't know, the Nespresso Vertuo brews coffee at a relatively low temperature because it uses centrifugal pressure to extract the magic from the beans, not boiling water. I love how it's immediately drinkable, but after 15 minutes it's not hot enough. This rambler is the perfect accompaniment for one of these machines and I highly recommend it!
