Bests & Worsts Reviews from Amazon

I've had this mug for a few months now, and use it daily. It gets some rough treatment (dropped, knocked over), and still works great. Highly recommended. Cons (all very minor): 1. Lid does not come apart completely for cleaning, so gunk could lurk in there somewhere. That said, I put the lid through the dishwasher and have yet to find any evidence of anything remaining behind after cleaning. No off taste, no bad smell. 2. If you turn the whole thing upside down and try to dispense coffee (as into a mug), coffee will shoot out of the two vent holes as well as the hole for drinking. Solution: don't do that. 3. If you overfill the mug and try to screw the cap on, you will have coffee coming out of the lid, the vent holes, the button, etc. Solution: don't do that. 4. If you take a drink and then tip the cup over, you can get one drop of coffee that will fall off of the cup. It basically collects on the rubber stopper if you didn't tip the cup upright before releasing the button. Solution: sit the cup upright before releasing the button, or just "burp" it one time to let the liquid drop back into the mug. You can then turn it upside down and shake it and nothing will go anywhere. Some other reviewers are griping about the cup dribbling, I don't see it. Just remember to take a sip, turn the cup back upright and THEN release the button. Or, press the button again for a second if you forget. Seriously. This is a non issue. Pros: 1. Read the cons. They all minor, two of them are operator error, one is no big deal, and the last is a simple problem with a simple solution. These are the only shortcomings I could find for this mug. Really. It's that good. 2. Hot stuff stays hot for hours. No, I don't have temperature readings. All I know is that I brew coffee at 5:45 and it is still nice and hot at 10. Good enough for me, not at all "lukewarm." 3. Zero mess. If it is dribbling you either got a lemon or you're doing it wrong. I wear a white shirt at work and I have yet to get a coffee stain with this mug. Spills and drips really annoy me, and this cup is 100% messless, unless you're using it wrong. 4. The turning lid/lock is awesome. Turn it closed and you can toss your mug in a bag and not have to worry about it leaking. Also, you can now leave your cup in a dirty environment (or take the lid off to refill it, and sit it upside down on the counter) without having to worry about keeping the drinking area clean. Someone was griping about having to unscrew the top to drink- sure, if it is closed. You don't have to close it for the cup to be spillproof. 5. Fits most normal sized cupholders. If Iever lose this cup, I'm buying another one just like it. I originally gave it 4 stars, but I upped it to 5 .... the only real ding is that the lid doesn't come apart 100%, but until I see some evidence of buildup in the innards somewhere, I don't think it warrants a 20% knockoff for that alone.
