    I bought two of these and they were great when they worked. Handwashed everytime.

    We had a mug similar to this one as a gift. It finally died, we bought two from Road Pro and did not heat right. Sent back twice no good results. We just used this one on a 3 week vacation and could not have been more satisfied. Thank You.

    JOYCE -- bristow, VA   3/1/2010
    Very good buy. Able to keep coffee pretty warm plugged into the car adapter. However, not as good used with the PC. All in all, worth the price.
    JEAN -- whispering pines, NC   2/8/2010
    The travel mug works great. Keeps my drink hot until it's all gone. The only complaint I have is the lid has a bad chemical odor.
    LINDA -- pryor, OK   1/4/2010
    did not keep coffee hot at all
    Thomas -- canada, Ontario, Ottawa   12/23/2009
    Just got the unit, Kept the coffee at a drinkable Temp for 2 hours then needed a refill . Twisty cord is a little anoying had to strech it out to fit nicely on the desk. Lid seemed to be a little loose when empty but has not leaked so the seal is working. Great product glad i bought 4.

    JOSEPH -- delta, OH   1/10/2009
    The USB connection barely keeps the mug warm. The lighter plug failed on first use.
