Contigo Autoseal Transit Stainless Steel Travel Mug, 16 Oz, Stainless Steel with Blue

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.

Calidad total, no se derrama nada y los líquidos permanecen caliente por muchas horas

I have two problems that made me need the best in spill proof. One is I'm constantly thirsty. To the point that my moith goes bone dry if I don't keep a drink near. Two is I have a nerve condition that i drop things w/o warning. Weve had to pull up carpets from the water damage from all the cups of coffee I've spilt. Ive had other Contigo cups that were almost perfect. But if they were not closed after sipping it would spill. Others closed as soon as I stopped drinking. But if it landed wrong the sip button would engage & it would spill. This new cup has a dual layer of protection. It will not release fluid unless the button is held firmly (but not so firm as to be hard to use), & they put a top on that blocks further spilling when it's twisted in place. So as soon as I can i turn the lid to lock . Even after the cup hits the ground it helps because even if it does hit the sip button during a fall I can reach down ,& twist the top thus ending any spill before it has time. Or after drinking it will be locked over to keep it protected. And stop dirt from getting on the lid. I hated taking travel bottles out because they could get so nasty. And be an embarrassment when the security guards checked my bags. Now they wont see sticky coffee & gunk. Just a clean bottle with a lid covering it. No more dropping drinks in stores & having to aplologize over ,& over for the mess. Oh, & the old Contigo lids were hard to clean. But this is just great. The inside workings now pop loose in one piece from being snapped into the cup & you wash it as a whole (the insides are held on by a latch that folds) & snap it back in after washing.

Best cup ever! I can not say that enough. I jave tried every sippy cup, mug, travel cup I have come across. I have a 8 y/o and a 3 y/o and then there's my husband... This cup can not accidentally spill! It does not leak. It does not pop open when your 3 year old drops or throws it. It does not leak in your 8 year olds book bag, sweat on his desk and get his work wet, or cause him to make weird slurpy noises that disrupt class and get you a note about your kids strange drinking noises for this teacher. This cup also does not have nasty cylicone straws you have to clean with expense and frustrating pipe cleaners that still don't stop the mildew. When your husband leaves this in his work truck for a week with hot chocolate in it (yes he used milk not water of course) and you open it up to a smell that could kill... you simply dump it outside and pop all the parts open and stick it I the dish washer (twice for good measure.) I have had this cup for a year now and have not had any issues with mildew or spills with this cup and I can honestly say it is the only cup I can say that about. I saw a review with a picture of mildew in the push button part. I have not had this issue I checked well. Maybe they hand washed and left it wet and soapy? I love the lock on the top that slides over to keep the mouth part clean and keep the bottom from being pressed. This is the easiest cleaning and most spill proof cup ever. The cup will also keep things cold or hot all day.
