Question: What is being done to correct the leaking issue persons are complaining about?
Document: The small size is perfect to fit in my diaper bag and in the car. Some of the others were just to big to be handy.I do have to say that mine started leaking today, but I really feel that this was just a fluke -these things are usually made really well. Maybe there was a rubber ring or something that came off. I haven't ever done anything to it but rinse it with water. I'm still rating it as a 5.
'Lastly, the damn thing leaks. IT LEAKS FOLKS. if there are 3 things to get right in a thermos, it's 1) be leak proof 2) keep my drink hot/cold for a long time and 3) have a good design. The leaking problem is my biggest issue... I would highly recommend looking at another thermos. Just my 2 cents.
I saw all of the great reviews, didn't see anything about leaking issues and wrongly assumed that this bottle had all the good stuff of the e5 without the one flaw.I am very disappointed.Do other vacuum insulated bottles have this same issue?I already tossed the box and had decided to keep it even though it has a dent on the bottom as perfection isn't that big of a deal to me... but being a dribble cup is kind of a deal breaker.
It's the perfect size for me. Sometimes I use it for hot tea or sometimes for cool beverages. I've had this for 3 months now and so far I don't have any leaking issue like some people mentioned. That might happen later...like with other thermos insulated bottles I had in the past, eventually they all start to leak maybe because the vacuum or plastic part start to get loose with usage. I guess nothing last forever. But so far so good.
I got this thermos for my boyfriend after reading TONS of reviews for different products. He's been using it for work and hunting and with both his drinks stay hot (or cold) all day. The safety switch (not sure if that's the correct terminology) is really a life saver too. Great product, if you are stuck on a decision go with this one!
After that ride, the o-ring got wet and no longer "sticks." Once you press the release button the lid flips up to an open hole accessing the contents. This is pretty easy to use and can definitely be done while cycling but i often just transfer the contents to my squeeze bottle.
I can't remember why I needed her to buy one so badly (free shipping, maybe?) but I had hyped it up to her, letting her know that I had done extensive research on which thermos was the best and that there were rave reviews about it. She was nonchalant about it and I had never really seen her use it.
Its weight is perfectly balanced for this, and it doesn't seem to matter if there's water in it or not. When it slaps into my hand, if I've done it right, my thumb will hit the button to open the lid. So picking it up, tossing it up, catching it, unlatching, and drinking become one continuous, fluid movement. It's not something I just could not do with any other bottle.
The gasket is soft, the exact size it needs to be, well designed. The surfaces it seals, both metal and plastic, are even, without any imperfections, it's a perfect fit. My guess would be one of the three: 1. Not tightening enough. 2. Overtightening. 3. Gasket is missing/slipped out of its correct place during washing, maybe somehow got torn or cut.
About 1/2" in diameter. And angled perfectly so as not to spill liquid unexpectedly before you tilt it to your mouth.6) If you want your drinks to stay their correct temperature longer, pre chill or heat the bottle and close the lid for 5 minutes before you fill it. That is, fill it with cold water, let it sit to attain the correct temperature inside -- then fill it with your cold beverage.
Answer: I have used these for years and the only time mine leaked was when the blue gasket in the lid fell out and i didn't notice.  Check the gasket.  It may need repalced or not be installed correctly.
