So these are terrible! Wouldn't recommend them to anyone. I know they are cheaper than some of the other alternatives, but not worth it. Spend the extra dollar or two to get the better quality. We have been using these for about 3 weeks now and both of them are in the trash. Both of them ended up leaking coffee everywhere. There are 2 main reasons why I do not recommend this product:
1. The lid is a little wider around the lip which causes you to have to tip the mug all the way up to get any coffee out. (Also there is no air escape so the coffee barely dribbles out).
2. The lid and the mug itself do not make a complete seal. Therefore, coffee drips out between the lid and the mug. This is a great combo with number 1 when you have the mug tipped all the way up, you are definitely getting coffee on your nice clean work shirt!!
These mugs are awful. The way the top is designed, it's very hard to drink from the cup without getting coffee on yourself. Really poor design. And, lucky me, I have two. Didn't send them back because I had washed them in the dishwasher before using, so now they just sit on the shelf. Do NOT buy these.
Purchased these as a xmas gift . Have not as yet put these tumblers into use so unable to rate how well they keep drinks warm or cold...Do have some concerns on how well constructed as the "insulating" rings that help prevent slippage are not well fitted and easily slip off the cup. I expect these cups will not last more than one or two uses. I will have to find some others that better fit the need for a good travel tumbler.
