Top quality
I like the feel of this water bottle. It is of good quality and easy to handle not bulky and I can easily hold onto it. It is attractive as well. It fits nicely into,the car beverage holder. It really does keep cold beverages cold even on a hot day. With the top securely on, I have never had it leak. I use a reusable straw in mine and it works great this way. I have another one that I have had for several years and wanted this one for when the other one is getting washed or I have another beverage in it. I keep it with me at all times so I get enough hydration.

Yeah man. It’s very good. I recommend it.
This is the best one I’ve ever had. It’s durable, steel so no plastic leeching, has silicone fittings that are easily removable for cleaning leaving nowhere for mold or gunk to get trapped. It’s everything I was looking for in a bottle. No leaks. I do think I overestimated the size and find myself rationing my water but that’s my fault and not the company’s. I will buy this in the larger size as well. My only complaint is that the rubber bottom pad comes off sometimes and I’m afraid I’ll lose it. The pad is super nice to have so I might end up just gluing it on or something. This is a really great bottle overall.

Awesome Water Bottle!
I love everything about this water bottle. The size is perfect for car drink holders. I like the removable silicone bottom, but it sometimes comes off in my bag or drink holder. I'm thinking about putting some glue on it to make it permanently adhere. Water stays cold for a long time and the drinking sprout is really nice. I especially like the easy twist of the screw off cap that's attached to the bottle because it make a nice loop holder for toting.

So grateful for these bottles.
I am not sure if these bottles are sold out because they are discontinued, or because they are popular. Either way, I don't usually give reviews but wanted to: Months ago, I decided to finally make the switch from plastic reusable water bottles to stainless steel. After a lot of research, I chose EcoVessel, and have been so happy that I did. Despite one design issue, I still regard these water bottles very highly and am so grateful for them. They're really beautiful. I've had the white, dark green, and dark gray. I primarily chose this brand because, I learned that most stainless steel water bottles still have plastic mouth spouts/plastic touching the water inside. This water bottle has two openings, but I only ever use the wide mouth opening, which is stainless, so I drink from stainless, not silicone. The only other comparable brands, have really uncomfortable metal handles for carrying, and, one was very expensive, because it required a separate purchase for an all-stainless lid (and one of those brands, people said the bottles smells inside…). I've been very happy with both the wide mouth opening and the carrying handle on these water bottles. They are very comfortable to carry. And, they keep water refreshingly cold (or drinks hot), something I didn't have with my former plastic bottles. I have only dropped them a couple of times, but they held up very, very well compared to my past Thermos brand carriers (which dented severely with one drop)—The first drop, no wear at all. The second, only a very, very minor ding on the edge of the small lid, such that you can’t even really see it. No scratches at all on the paint from use, only a couple very small marks this week on the white bottle (none before now), maybe from pen or something; that’s after four months of use. It still looks good. The only drawback, is that the boot on the bottom is very shallow, so it comes off sometimes. I've had three of these bottles; the white one in particular has a boot that is very loose, and still so after I exchanged it for that reason (the second was better, but still comes loose). I've also had the dark green boot come off the bottle. Thankfully, each time they've come off, I've been able to find it and put it back on (including today, but I thankfully found it outside of my car). But that is a problem. I think if the brand logo were put higher up on the bottle, instead of the bottom, then the boot could be made deeper, to stay on better. Even despite that issue, I still love these bottles and still give them a very high rating, so that says a lot. One minor shipping issue: I had to reorder the green one a few times because it arrived scratched. But I did then get one that was great. I do hope this or a very similar bottle will continue to be available in the future, with the same look and stainless interior/lid.

Perfect!
There is nothing I don't like about Ecovessel water bottles. I like the company and what they stand for, I like the quality and look of the product, I like the features, I like how it holds up against other brands. This is my first Ecovessel bottle and it is completely leak-proof (after traveling a lot through vastly different altitudes and pressure changes). It holds 24 ounces, which means it doesn't have to be refilled as often as typical 2-cup bottles, and it is better quality than my last water bottle brand (which starts with a T and is 3 letters long). I put in cold water and a few ice cubes at the beginning of my trip and as long as the water I put into it was reasonably cool (chilled, cold tap, plastic bottled water that had been sitting in the car but wasn't hot yet), it stayed below ambient temperature up until the very tail of the 6-day trip. Some people have complained about the strap that attaches the cap, but I am not sure why and had no issues with it. The removable strainer and silicone bumper on the bottom are nice features, but the bottle won't fit in a typical car cup holder with the bumper on, so it's nice that it can be removed. The lid/neck size is not compatible with other brands, so don't count on switching them around. It would be nice to have a snap cap or a straw lid that didn't leave the mouthpiece exposed, but the twist cap works just fine and I'm really grateful to have a bottle that keeps my drinks out of contact with plastic (at least while it is in the bottle).

Near perfection
If you’re looking for a solid water bottle with a comfortable spout that has just about everything you could think of for options this is hands-down, the best water bottle I’ve ever experienced. From the solid construction with great cooling and heat ability to the simple modification at the bottom, indentation for your thumb to be slightly inset for better grip. This water bottle has really thought of everything to make your drinking experience as perfect as you could get. I really find the subtle details wonderful on this bottle at the end of the day it still has to do its workhorse job, which is not leak and keep water cold or hot this bottle Has done both for me granted, it’s been a short amount of time however, after decades of looking for the perfect water bottle, this is the closest one I could find and I’m never changing unless something better comes along in the industry. I would highly recommend trying and if you’re like me, you’ll probably end up buying several for different uses in your life. They have a big one called the boss which is 64 ounces I use that as well and some smaller ones but nothing beats the practicality and simplicity of this water bottle.

Ok bottle
This water bottle is ok- my main complaints are that the inside of the top lid discolored to a rusty, reddish tint. I don't know what to think of that. Also, that same top screw-on lid is not insulated. If it sits in the sun or in a hot car, the water at the top will be warm- it's happened to me. The silicon drinking spout can get a bit smelly so make sure to wash it every day if you buy it. I actually do not like the two part lid- I'd rather just have one without the silicon spout. It looks nice and fits in my car cup holder well. I like the silicon part at the bottom for protection and stability in a cup holder, but sometimes it falls off. If I could give the bottle 3.5 stars I would. It's just not quite a 4 for me. I haven't used the strainer part yet- that might come in handy for some.

Wunderschön
Wunderschöne Flasche, ich bin richtig froh, diese gekauft zu haben. Leider habe ich beim Auspacken gesehen, dass sich ein Kratzer in der Oberfläche befindet, was ich sehr schade finde. Gibt es die Möglichkeit einer Preisreduktion? Ich habe sie bis jetzt noch nicht verwendet und kann nichts über die Kühl- oder Wärmeeigenschaften sagen.
