This travel mug is great.  I love that it is stainless and will not absorb anything that is put in it (like coffee).  It is easy to wash and is light weight.  The top has a lock on it, so it will not allow the button that opens the top to accidently get pushed.  It also has a great handle that will lay flat if not needed, or swivel up for ease in carrying.  I would highly recommend this travel mug!
