I love this mug, keeps my coffee hot all day. Best handle design I've seen on a mug! The only item I did not like is the lip you sip your coffee from, it's a bit too narrow and I wish it were wider to mimic more like sipping from a coffee cup. I still give it 5 stars and you will be happy with your purchase. I was also happy that they have a 20oz mug (16oz too small for me). The cap is easy to take apart and clean. I've purchased more than 10 mugs in my lifetime, this one has the best handle design and is one of the easiest to clean the cap.
