Question: Is the liquid inside the container exposed to any plastic from the lid? Is the tea strainer made from a plastic mesh or a metal mesh?
Document: I bought this bottle about six months ago from Amazon. As advertised the liquid stays cold for a very long time. That part of the bottle is great. The first problem came with metal screen inside the lid that is supposed to prevent the ice from coming out. It broke after a month. Today my bottle started leaking through the lid as a stopper of some kind has gone missing. I won't be able to use this bottle any more because I place the bottle in my work bag with computers and papers.
Purchase this in Jaunary of 2011. I use it to make hot chocolate and tea. It keeps the water hot.warm for many hours, but doesn't it it hot over night - in the morning it's still warm, but not super hot. I like the strainer as it allows me to keep the tea leaves out of my mug. The lid fits tightly and doesn't drip. It cleans well - no residue smells, although like any other thermos, long use of tea will stain the inside.
Accidently leaving drinking water in the car during Minnesota's winter is usually the end for a water bottle, but these can survive overnight freezing temperatures without the water inside freezing! Unfortunately the metal ring over the plastic cap wears off within a few months. I think it might be more bulky than a Klean Kanteen bottle, but the tea screen inserts are really worth it -- which could also be used to keep ice cubes & lemon wedges as well as tea bags.
Great product. Stays cold, 2 sizes of openings and a metal mesh insert for tea, etc. It is an all around great product.
Plus, the hole is really nicely sized allowing a good gulp for a man to take.When you take the whole top off the whole is really sized well, allowing ice to be easily put in. There is a mesh basket that attaches to the inside, right under the cap, this is perfect for tea or coffee and an amazing innovation, very clever. Hubby and I am both really impressed with this item and would highly recommend it to anyone, especially those that travel.
This is a Nice Looking and Well Made Product. However, it is metal and I personally found the water tastes like the metal when you drink. I would not purchase again-I think I would go with the Plastic.
Normally most Stainless Steel products are rugged and can handle abuse, but NOT these Vessels.The day I purchased one of my Eco-Vessel Boulder 17's I filled a new bottle with hot tea and while carrying it across the driveway I dropped it, about 3 feet from my waist to the ground. It acquired about 15 small to medium dents, tore the paint off, and made the metal cap look like someone stuffed it down a running garbage disposal.
The Thermos uses a hardened, thick heavy duty plastic with rubber rings for the cap. The thick sides of the cap, which is not at all impeding to the user, cover the top of the bottle and about two inches of the sides of the bottle's top, which is itself thickened some. Whereas, the Eco Vessel has cheaper, thinner plastic with a steel metal strip on the lid that covers a smaller portion of the top of the bottle when screwed on.
one bottle was bent on the rim (shabby workmanship & inspection)I guess I didn't read the fine print close good enough not made in US. (my fault)has plastic mouthpiece. in my opinion if you have a stainless steel vessel & drink the content through a plastic straw you have defeated the purpose for having the stainless steel.dose keeps liquid cold.
The Eco Vessel is excellent for insulating the liquid inside. The one major flaw is the plastic strap connecting the cap to the bottle:  every time you put the bottle-mouth to your mouth to take a sip, the cap and plastic strap will hit your head. And the only way to  prevent this would be to cut the strap off entirely.
Answer: yes
