Review on The Bags Under My Eyes Are Designers Sarcastic Ceramic Coffee Travel Mug 12 Oz. With Sealed BPA Free Lid And Dishwasher Safe - Funny Saying - Novelty Travel Coffee Mug For Women by Antonio Lemm

Very nice quality, keeps both cold and hot drinks at temperature for 20 to 30 minutes. Very nice ceramic finish inside and out. A bargain for the price. The cover and seal work very well, nice fit and seal, no spills or liquid leaks around the cover. One minor problem is the small ceramic vent hole in the bottom traps water when cleaned in the dish washer with no way to assure that all of the water will come out and dry. Therefore, I hand wash and I am careful to keep water away from the hole. Since purchasing this mug, I have seen similar mugs with a rubber seal applied to the vent hole. Maybe the manufacturer will look into similar for this mug.
