I always enjoy having a new cup and getting this  stainless steel mug SM-VS83XA is a great decision. 

I'm in love it! It is easy to handle, sleek and very functional! 
Leak Proof, I lock the lid on and I can shake it, turn upside down and nothing comes out, it’s amazing.

Now, I put it to the test...I made fresh coffee and left it home and went to town came back 3 hours later tested it and I will be darned it was piping hot !!!!
Yes I highly recommend this product! No more cold coffee for me! I can use it for cold drinks too but this is my coffee go to!
