I am loving this tumbler.  It really does keep your drink hot for a long time.  After an 8 hour day, my coffee was actually still a little warm (was busy and didn't have much time to drink anything).  It is much heavier than my Tervis, but still love it.  The mouth-hole does leak a little when it is closed, but not too bad.  I also had my name engraved on it, so that ability is nice, too.
