12 Oz Stainless Steel Tumbler
For a start I share my experience:

I was skeptical about this tumbler based on the reviews and pictures I saw here. But I ordered this 12 Oz Stainless Steel Tumbler in the LAVENDER color and couldn't be any happier with my purchase! 

My coffee stays warm from the first sip to the last. I also like the lid. People here complain that it leaks but it’s not designed to be leak-proof, just splash-proof. I can remove it easily to clean it thoroughly. 

Actually, this 12 oz Tumbler is exactly what I needed. It keeps my coffee hot during my commute and at work while sitting at my desk. Even though I put a hot beverage in it, the insulation kept it from getting too hot on my hands (problems I've had in the past with different products). The lid also has a sliding cover which is great. When I hit bumps, the coffee stayed inside the tumbler.

It should be noted that this mug in the market is known as two more:  12 Oz Stainless Steel Coffee Mug and  12 Oz Stainless Steel Cup.
